AS1360
1.5µA Low-Power, Positive Voltage Regulator

Datasheet
1 General Description
The AS1360 low-power, positive voltage regulator was
designed to deliver up to 250mA while consumin g only
1.5µA of quiescent current. The device is available in
fixed output voltages of 1.8, 2.1, 2.5, 3.0, 3.3, and 5.0V.
The device features integrated short-circuit and overcur-
rent protection.
The wide input voltage range, low-drop out voltage, and
high-accuracy output voltage makes the device perfectly
suited for 2- and 3-cell battery-powered and portable
applications.
The low dropout voltage (650mV) prolongs battery life
and allows high current in small applications when oper-
ated with minimum input-to-output voltage differentials.
The device features very stable output voltage (using
only 1µF tantalum or aluminum-electrolytic capacitors),
strict output voltage regulation tolerances (±0.5%), and
excellent line-regul ation.
The AS1360 is available in a 3-pin SOT23 package.
