AS1360
1 . 5 µ A L o w - P o w e r, P o s i t i v e Vo l ta g e R e g u l a t o r
1 General Description
The AS1360 low-power, positive voltage regulator was
designed to deliver up to 250mA while consuming 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-dropout 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-regulation.
The AS1360 is available in a 3-pin SOT23 package.
