AP78L05 is a three terminal positive regulator available with fixed output voltages. 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 system, instrumentation, HiFi, and other solid state electronic equipments. The AP78L05 is available in the plastic TO92-3L and SOP-8L package 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 is a fixed‑mode 5 V three‑terminal positive regulator. It provides a regulated 5 V output with tolerances of +5%, supports output currents in excess of 100 mA, and includes internal thermal overload, short‑circuit, and safe‑area protection. The device is offered in plastic TO92‑3L and plastic SOP‑8 low‑profile packages.
Typical applications include communication equipment, CD‑ROM/DVD players, and set‑top boxes. Ordering information lists part numbers for each package, and the datasheet also contains pin assignments, electrical characteristics, and mechanical dimensions.
