AN80xx/AN80xxM Series
3-pin, positive output, low dropout voltage regulator (50 mA type)
a73 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.
a73 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
