It can be used in a wide range of applications. It can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. The voltages available allow the AP78L05 to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipments. The AP78L05 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.

The AP78L05 fixed voltage regulator series has built-in thermal overload protection which prevents the device from being damaged due to excessive junction temperature. The regulator also contains internal short-circuit protection which limits the maximum output current, and safe-area protection for the pass transistor which reduces the short-circuit current as the voltage across the pass transistor is increased.
