3A Low Dropout LDO
EM5103
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.
