AS1360
1.5µA Low-Power, Positive Voltage Regulator
1 General Description
The AS1360 low-power, positive voltage regulator was designed to
deliver up to 250mA while consuming only 1.5µA 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 1µF 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.
