AN78N00 Series

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

■ Overview

The AN78N00 ser ies is 3-pin fix ed positi ve output v olt­age regulators. Stabilized fixed output v olta ge is obtained
from unstable DC input voltage without using any exter­nal components. 12 types of fixed output v oltage 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
