General Description
EM5102A is a 2A 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 2A output current and ultra-low-drop output voltage as
well as full protection functions. VOUT can be as low as 0.8V.
.
