AN78N00 Series

3-pin Positive Output Voltage Regulator (300mA Type)

■ Overview

The AN78N00 series is 3-pin fixed positive output voltage regulators. Stabilized fixed output voltage is obtained from unstable DC input voltage without using any external components. 12 types of fixed output voltage are available ; 4V, 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V, 18V, 20V and 24V. They can be used widely in power circuits with current capacitance up to 300mA.

■ Features

•No external components

•Output voltage : 4V, 5V, 6V, 7V, 8V, 9V, 10V, 12V, 15V,

18V, 20V, 24V

•Short-circuit current limiting built-in

•Thermal overload protection built-in

•Output transistor safe area compensation
