AME8753
Description
The AME8753 dual, low dropout, linear regulators operate from V OUT+VDROPOUT to 5.5V input and deliver up to 500m A / 500m A output current each. Low dropout voltage 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 shutdown and current fold-back to prevent device failure under the "Worst" operating conditions.
