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.
