AP78L12

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.
