1 General Description

The AS1360 low-power, positive voltage regulator was designed to

deliver up to 250mA while consuming only 1.5 A of quiescent cur-

rent. The device is available in fixed output voltages of 1.8, 2.1, 2.5,

3.0, 3.3, 4.0, 4.5 and 5.0V.

The device features integrated short-circuit and overcurrent protec-

tion.

The wide input voltage range, low-dropout voltage, and high-accu-

racy 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 operated with minimum

input-to-output voltage differentials.

The device features very stable output voltage (using only 1 F tanta-

lum or aluminum-electrolytic capacitors), strict output voltage regula-

tion tolerances (±0.5%), and excellent line-regulation.

The AS1360 is available in a 3-pin SOT23 package.
