AN79N00 Series

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

■ Overview

The AN79N00 series is 3-pin fixed negative output voltage regulators. Stabilized fixed output voltage is obtained from unstable DC input voltage without using any external components. 12 types of 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
