3-pin positive output voltage regulator (100 mA type)

Panasonic Corporation 

Voltage Regulators

AN78Lxx/AN78LxxM Series

3-pin positive output voltage regulator (100 mA type)

I Overview

The AN78Lxx series and the AN78LxxM series are 3-

pin fixed positive output type monolithic voltage regula-

tor.

A stabilized fixed output voltage is obtained from an

unstable DC input voltage without using any external

parts. 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 as power circuits with a current

capacity of up to 100mA.

I Features

• No external components

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

18V, 20V, 24V

• Built-in overcurrent limit circuit

• Built-in thermal overload protection circuit
