description this series of fixed-negative-voltage mono lithic integrated-circuit voltage regulators is designed to complement series mik7800 in a w i de range of applications. these applications include on-card regulation for eliminat ion of noise and distribution problems as sociated w i th single point regulation. each of thes e regulators can deliver up to 1.5 amperes of output current. the internal current li miting and thermal shutdow n features of these regulators make them essent ially immune to overload. in addi tion to use as fixed-voltage reg ulators, these devices can be used w i th external components to obtain adjustable output voltages and current and also as the pow er pass element in precision regulators. features ? 3-terminal regulators ? output current up to 1.5 a ? no external components ? internal thermal overload protection ? high pow e r dissipation capability ? internal short-circui t current limiting ? output transistor safe area compensation package information package t o -220 (top view ) ty pical application data 1.5 a regulator w hen using a negative regulator, by pass capacitors are a must on both the input and output. recommended values are 2 f on the input and 1 f on the output. it is considered good practice to include a 0.1 f capacitor on the output to improve the transient response (fig. 1) . these capacitors may my lar, ceramic, or tantalum, provided that they have good high frequency characteristics. mi k 7 9 0 0 $v in $v ou t 2 f 0. 1 f 1f 3 2 1 figure 1. negative regulator absolute maximum ratings over operating temperature r ange (unless otherw i se noted) p a r a m e t e r m a x i m u m units m i k 7 9 2 4 - 4 0 input voltage all others -35 v continuous total dissipation at 25 c free-air temperature 2 continuous total dissipation at (or bellow ) 25 c case temperature 15 w operating free-air, case, or virtual junctions temperature range 0 to 150 storage temperature range -65 to 150 lead temperature 3.2 mm (1/8 inch) from case for 10 seconds 260 c recommended operating conditions p a r a m e t e r m i n m a x u n i t s m i k 7 9 0 5 - 7 - 2 5 m i k 7 9 0 6 - 8 - 2 5 m i k 7 9 0 8 - 1 0 . 5 - 2 5 m i k 7 9 1 2 - 1 4 . 5 - 3 0 m i k 7 9 1 5 - 1 7 . 5 - 3 0 m i k 7 9 1 8 - 2 1 - 3 3 input voltage v i m i k 7 9 2 4 - 2 7 - 3 8 v output current, i o 1 . 5 a operating virtual junction temperature, t j 0 1 2 5 c page 1 of 5 1.5 a negative voltage regulator 79xx et-
