MIC35302

MIC35302 3A, Low Voltage µCap LDO Regulator General Description The MIC35302 is a 3A 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 MIC35302 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 MIC35302 LDO include current limiting and thermal protection, and reverse current and reverse battery protection. Also logic (active-HIGH) enable pin is included. The MIC35302 is available in a 5-pin power D-Pak package (TO-252) with an operating temperature range of –40°C to +125°C.
