1/29 1a, 0.5v low input voltage, high speed ldo regulator XC6602 series general description the XC6602 series is a low voltage input (0.5v) operation and provides high accuracy 15mv/ 20mv and can supply large current efficiently due to its ultra low on-resistance even at low output voltages. the series is ideally suited to the applications which require hi gh current in low input/output voltages and consists of a nch driver transistor, a voltage reference, an error amplifier, a cu rrent limiter, a fold-back circuit, a thermal shutdown (tsd) ci rcuit, an under voltage lock out (uvlo) circuit, a soft-start circuit and a phase compensation circuit. output voltage is selectable in 0.1v increments within a range of 0.5v to 1.8v using laser trimming technology and ceramic capacitors can be used for the output stabilization capacitor (c l ). the inrush current (i rush ) from v in to v out for charging c l at start-up can be reduced and makes the v in stable. the soft-start time is optimized internally. the ce function enables the output to be turned off and the seri es to be put in stand-by mode resulting in greatly reduced power consumption. at the time of entering the stand-by mode, the series enables the electric charge at the output capacitor (c l ) to be discharged via the internal switch. as a result the v out pin quickly returns to the v ss level. the ce pull-down function keeps the ic to be in stand-by mode even if the ce pin is left open. features maximum output current : 1a (1.3a limit) on resistance : 0.15 ? v bias =3.6v,v out =1.2v bias voltage range : 2.5v 6.0v input voltage range : 0.5v 3.0v output voltage range : 0.5v 1.8v (0.1v increments) output voltage accuracy : 0.015v v out 1.2v 0.020 v out R 1.2v ripple rejection : 60db f=1khz (v bias_psrr ) 75db f=1khz(v in_psrr ) low power consumption : 100 a (v bias ), 6.5 a(v in ) v out =1.2v stand-by current : 0.01 a (v bias ), 0.01 a (v in ) under-voltage lockout : 1.8v (v bias ), 0.4v (v in ) thermal shutdown : 150 detect, 125 release protection circuit : fold-back current limit, tsd, uvlo function : built-in soft-start ce pull-down (active high) c l auto discharge operating ambient temperature : -40 +85 output capacitor : ceramic capacitor compatible (2.2 f) packages : usp-6c, sot-26w, sot-89-5 environmentally friendly : eu rohs compliant, pb free typical application circuit etr03045-004 applications mobile phones / smart phone digital still cameras / video camera note pc / tablet pc e-book reader wireless lan typical performance characteristics dropout voltage vs. output current XC6602x121mr-g 0 50 100 150 200 250 0 200 400 600 800 1000 output current: i out (ma) dropout voltage: vdif(mv) vbias=3.3v vbias=3.6v vbias=5.0v v ce =v bias , c bias =c in =1.0f, c l =2.2 f ta=25 www.datasheet.co.kr datasheet pdf - http://www..net/

6/29 XC6602 series the voltage divided by resistors r1 and r2 is compared with the internal reference voltage by the error amplifier. the v out pin is then driven by the subsequent out put signal. the output voltage at the v out pin is controlled and stabilized by a system of negative feedback. v bias pin is power supply pin for output voltage control circuit, protection circuit and ce circuit. also, the v bias pin supplies some current as output current. v in pin is connected to a driver transis tor and provides output current. in order to obtain high efficient output current through low on-resistance, please take enough v gs (=v bias ? v out(e) ) of the driver transistor. figure1: XC6602 series, type a with the XC6602 (type a), the inrush current (i rush ) from v in to v out for charging c l at start-up can be reduced and makes the v in stable. as for the XC6602, the soft-start time in the type a is optimized internally. on t he other hand, the type b of the XC6602 does not have the soft-start time function. the XC6602 series includes a combination of a fixed current lim iter circuit and a foldback short-circuit protection. when the output current reaches the current limit, t he output voltage drops and this operation makes the output current foldback to be decreased. when the junction temperature of the built-in driver transistor reaches the te mperature limit, the thermal shutdown circuit operates and the driver transistor will be set to off. the ic resumes its operation when the thermal shutdown function is released and the ic?s operation is automatically restored because the junction te mperature drops to the level of the thermal shutdown release temperature. when the v bias pin and v in pin voltage drops, the output driver transistor is se t to off by uvlo function to prevent false output caused by unstable operation of the internal circuitry. when the v bias pin voltage and the v in pin voltage rises at release voltage, the uvlo function is released. the driver transistor is turned on and start to operate voltage regulation. operational explanation www.datasheet.co.kr datasheet pdf - http://www..net/
7/29 XC6602 series the XC6602 internal circuitry can be shutdown via the signal to the ce pin. in shutdown mode with ce low level voltage, the v out pin will be pulled down to the v ss level via c l discharge resistance (r dchg ) placed in parallel to r1 and r2. the ce pin has pull-down circuitry so that ce input current fl ows during ic operation. if the ce pin voltage is taken from v bias pin or v ss pin then logic is fixed and the ic will operate normall y. however, supply current may increase as a result of through current in the ic's internal circuitry when medium voltage is input. XC6602 series can quickly discharge the el ectric charge at t he output capacitor (c l ) via the internal transistor located between the v out pin and the v ss pin when a low signal to the ce pin which enables a whole ic circuit put into off state. when the ic is disabled, electric charge at the output capacitor (c l ) is quickly discharged so that it could avoids malfunction. discharge time of t he output capacitor (c l ) is set by the c l auto-discharge resistance (r dchg ) and the output capacitor (c l ). by setting time constant of a c l auto-discharge resistance value (r dchg ) and an output capacitor value (c l ) as ( = c l x r dchg ), the output voltage after discharge via the internal transistor is calculat ed by the following formula. please also note r dchg is depended on v bias . when v bias is larger, r dchg is smaller. v = v out(e) e -t/ or = ln v out(e) / v (v: output voltage after discharge, v out(e) : initial output voltage, t: discharge time, : c l auto-discharge resistance r dchg c l output capacitance with the XC6602 series, a stable output voltage is achievable even if used with low esr capacitors, as a phase compensation circuit is built -in. the output capacitor (c l ) should be connected as close to v out pin and v ss pin to obtain stable phase compensation. values required for the phase compensation are as the table below. for a stable power input, please connect an bias capacitor (c bias ) between the v bias pin and the v ss pin. also, please connect an input capacitor (c in ) between the v in pin and the v ss pin. in order to ensur e the stable phase compensation while avoiding run-out of valu es, please use the capacitor (c bias , c in , c l ) which does not depend on bias or temperature too much. the table below shows recommended values of c bias , c in , c l . chart 1 recommended values of c bias, c in, c l (min.) notes on use 1. for temporary, transitional voltage dr op or voltage rising phenomenon, the ic is liable to malfunction should the ratings be exceeded. 2. where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. please keep the resistance low for the v bias , v in and v ss wiring in particular. 3. please wire the c bias , c in and c l as close to the ic as possible. 4. capacitances of these capacitors (c bias , c in, c l ) are decreased by the influences of bias voltage and ambient temperature. care shall be taken for capacitor selection to ensure stability of phase compensation from the point of esr influence. 5. when it is used in a quite small input / output dropout voltage, output may go into unstable operation. please test it thoroughly before using it in production. 6. torex places an importance on improvi ng our products and their reliability. we request that users incorporate fail -safe designs and post-aging protection tr eatment when using torex products in their systems output voltage range bias capacitor input capacitor output capacitor v out(t) c bias c in c l 0.5v 1.8v 1.0 f 1.0 f 2.2 f operational expl a nation (continued) www.datasheet.co.kr datasheet pdf - http://www..net/
