AAT3244
300mA Adjustable Dual CMOS
Low Voltage LDO Linear Regulator
3244.2007.08.1.1

PowerLinear
General Description
The AAT3244 is a dual, low input voltage, low
dropout (LDO) linear regulator with two Power OK
(POK) outputs. Two integrated regulators provide
high power outputs of 300mA from an input voltage
range of 1.8V to 5.5V.
Two POK pins provide open drain signals when
their respective regulator is within regulation. The
AAT3244 has independent voltage inputs and
enable pins for increased design flexibility. The
device features a very low quiescent current (typi-
cally 85μA) and low dropout voltages (200mV at
full load), making it ideal for portable applications
where battery life is critical.
The AAT3244 is available in a space-saving, Pb-free
12-pin TSOPJW package and is capable of opera-
tion over the -40°C to +85°C temperature range.
