SURFACE MOUNT POSITIVE ADJUSTABLE VOLTAGE REGULATOR
Three Terminal, Adjustable Voltage, 1.0 Amp Precision Positive Regulator In A Hermetic Surface Mount Package
FEATURES
* * * * * * Hermetic Surface Mount Package Adjustable Output Voltage Built-In Thermal Overload Protection Short Circuit Current Limiting Product Is Available Hi-Rel Screened Electrically Similar To Industry Standard Type LM117HV
DESCRIPTION
This three terminal positive regulator is supplied in a hermetically sealed surface mount package. All protective features are designed into the circuit, including thermal shutdown, current limiting and safe-area control. With heat sinking, they can deliver 1.0 amp of output current. This unit features output voltages that can be trimmed using external resistors, from 1.2 volts to 57 volts.

Notes: 1. Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used. Changes in output voltage due to heating effects must be taken into account separately. 2. If not tested, shall be guaranteed to the specified limits. 3. The * denotes the specifications which apply over the full operating temperature range.
