General Description

EM5109 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 1.05V

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. The

other features include soft start, current limit protection,

Power-On-Reset function, and over temperature

protection. The EM5109 is available in PSOP-8 and

DFN3X3 package.
