s Overview

The AN78N00 series is 3-pin fixed positive output volt-

age regulators. Stabilized fixed output voltage is obtained

from unstable DC input voltage without using any exter-

nal components. 12 types of fixed output voltage are avail-

able ; 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.

s Features
