MIC35152
1.5A, Low Voltage µCap LDO Regulator
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.
