The AP78L12 of three terminal positive regulators is available

with fixed output voltages making them useful in a wide range of

applications. These regulators can provide local on card

regulation, eliminating the distribution problems associated with

single point regulation. The voltages available allow the AP78L12

to be used in logic system, instrumentation, HiFi, and other solid

state electronic equipment.

The AP78L12 is available in the plastic TO92-3L package, the

plastic SOP-8L package using industrial standard package

technology. With adequate heat sinking the regulator can deliver

100mA output current. 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. If

internal power dissipation becomes too high for the heat sinking

provided, the thermal shutdown circuit takes over preventing the

IC from overheating.

Well suited for a wide range of applications, such as:

•

Lighting Ballast

•

STB

•

Power supply

•

Audio Equipment
