EM5105

1A Low Dropout LDO

General Description

EM5105 is a 1A 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 1.1V for providing current to output.

It features 1A 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, under

voltage

protection,

current

limit

protection,

Power-On-Reset function, and over temperature

protection. The EM5105 is available in DFN3x3-10L

package.
