General Description

The MIC35152 is a 1.5A low-dropout linear voltage

regulator that provides a low voltage, high current output

with a minimum of external components. It offers high

precision, ultra-low dropout (600mV over temperature),

and low ground current.

The MIC35152 operates from an input of 2.25V to 6.0V. It

is designed to drive digital circuits requiring low voltage at

high currents (i.e., PLDs, DSPs, micro-controllers, etc.),

providing an adjustable output voltage from 1.24V to 5.4V.

Features of the MIC35152 LDO include current limiting

and thermal protection, and reverse current and reverse

battery protection. Also logic (active-HIGH) enable pin is

included. The MIC35152 is available in a 5-pin power

D-Pak package (TO-252) with and operating temperature

range of –40°C to +125°C.
