13-1) REGULATOR

3-TERMINAL 1A POSITIVE
VOLTAGE REGULATORS
The KA78XX series of three-terminal
positive regulators are available in the TO-
220 package and with several fixed output
voltages, making them useful in a wide
range of applications. Each type employs
internal current limiting, thermal shut-down
and safe area protection, making it
essentially indestructible. If adequate heat
sinking is provided, they can deliver over
1A output current. Although designed
primarily as fixed voltage regulators, these
devices can be used with external
components to obtain adjustable voltages
and currents.
■FEATURES
Output Current up to 1A
Output Voltages of 5; 6; 8; 9; 10; 11; 12;
15; 18; 24V
