EM5103

3A Low Dropout LDO

General Description

EM5103 is a 3A low dropout linear regulator

designed

for low dropout and high current

applications. This device works with dual supplies,

a control input for the control circuitry and a power

input as low as 1.2V for providing current to output.

It features 3A output current and ultra-low-drop

output voltage as well as full protection functions.

VOUT can be as low as 0.8V.
