SFF00007CEB

AN80xx/AN80xxM Series

3-pin, positive output, low dropout voltage regulator (50 mA type)

I Overview

The AN80xx series and the AN80xxM series are 3-

pin, low dropout, fixed positive output type monolithic

voltage regulators. Since their power consumption can

be minimized, they are suitable for battery-used power

supply and reference voltage. 13 types of output voltage

are available; 2V, 2.5V, 3V, 3.5V (SSIP003-P-0000 only),

4V, 4.5V, 5V, 6V, 7V, 8V, 8.5V, 9V, and 10V.

I Features

• Input/output voltage difference: 0.3V max.

• Output current of up to 50mA

• Low bias current: 0.6mA typ.

• Output voltage: 2V, 2.5V, 3V, 3.5V (SSIP003-P-0000

only), 4V, 4.5V, 5V, 6V, 7V, 8V, 8.5V, 9V, and 10V

• Built-in overcurrent protection circuit
