AN79N00 Series

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

s Overview

The AN79N00 series is 3-pin fixed negative output volt-

age regulators. Stabilized fixed output voltage is obtained

from unstable DC input voltage without using any exter-

nal 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.

s 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
