MIC69502
5A, Low V IN , Low V OUT μCap LDO
Regulator
General Description
The MIC69502 is a 5A, low dropout linear regulator that
provides low voltage high current outputs with a minimum
of external components. It offers high precision and ultra
low dropout of 500mV under worst case conditions.
The MIC69502 operates from an input voltage of 1.65V to
5.5V. It is designed to drive digital circuits requiring low
voltage at high currents (i.e. PLDs, DSP, microcontroller,
etc.). The MIC69502 output is adjustable to a minimum of
0.5V.
The μCap design of the MIC69502 is optimized for stability
with low value low-ESR ceramic output capacitors.
Protection features of the MIC69502 include thermal
shutdown and current limit protection. Logic enable and
error flag pins are also available.
The MIC69502 is offered in the space-efficient S-PAK
