STMicroelectronics 

L78S00

SERIES

2A POSITIVE VOLTAGE REGULATORS

. OUTPUT CURRENT TO 2A

. OUTPUT VOLTAGES OF 5 ; 7.5 ; 9 ; 10 ; 12 ; 15 ;

18 ; 24V

. THERMAL OVERLOAD PROTECTION

. SHORT CIRCUIT PROTECTION

DESCRIPTION

The L78S00 series of three-terminal positive regu-

lators is available in TO-220 and TO-3 packages

and with several fixed output voltages, making it

useful in a wide range of applications. These regu-

lators can provide local on-card regulation, eliminat-

ing the distribution problems associated with single

point regulation. Each type employs internal current

limiting, thermal shut-down and safe area protec-

tion, making it essentially indestructible. If adequate

heat sinking is provided, they can deliver over 2A

output current. Although designed primarily as fixed

voltage regulators, these devices can be used with

external components to obtain adjustable voltages

and currents.
