AME8753 Datasheet, PDF (1/11 Pages) Analog Microelectronics – Low Dropout 500mA / 500mA Dual CMOS LDO Regulator

AME, Inc.
AME8753
Low Dropout
500mA / 500mA Dual CMOS LDO Regulator
n General Description
The AME8753 dual, low dropout, linear regulators op-
erate from V_OUT+V_DROPOUT to 5.5V input and deliver up to
500mA / 500mA output current each. Low dropout volt-
age and low quiescent current(70µA typ.)make them ideal
for battery applications.
The AME8753 is available with a wide variety of voltage
options as standard and can be trimmed to 2% accuracy.
For protection purpose, AME8753 has both thermal shut-
down and current fold-back to prevent device failure under
the "Worst" operating conditions.
