The AP78LXX Series is a three terminal positive regulator

available with fixed output voltages from 5V, 8V and 12V, making

them useful in a wide range of applications. When used as a

Zener diode/resistor combination replacement, the AP78LXX can

improve output impedance by two orders of magnitude, and lower

quiescent current . These regulators can provide local on card

regulation, eliminating the distribution problems associated with

single point regulation. The voltages available allow the

AP78LXX's to be used in logic systems. Instrumentation, HiFi

and other solid state electronic equipment.

The AP78LXX is available in the plastic TO92-3L, SOT89-3L and

SOP-8L using industrial standard package technology. The

regulator can deliver 100mA output current with adequate heat

sinking. Current limiting is included to limit the peak output

current to a safe value. Safe area protection for the output

transistors is provided to limit internal power dissipation. Thermal

overload protection is integrated to prevent the IC from overheat

due to abnormal condition.
