General Description

The MIC69101/103 is the 1A output current member of the

MIC69xxx family of high current, low voltage regulators,

which support currents of 1A, 1.5A, 3A, and 5A. The

MIC69101/103 operates from a single low voltage supply,

yet offers high precision and ultra-low dropout of 500mV

under worst case conditions.

The MIC69101/103 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.). These regulators are available in

adjustable and fixed output voltages including 1.8V. The

adjustable version can support output voltages down to

0.5V.

The µCap design of the MIC69101/103 is optimized for

stability with low value low-ESR ceramic output capacitors.

Features of the MIC69101/103 include thermal shutdown

and current limit protection. Logic enable and error flag

pins are also available.

The MIC69101/103 is offered in a tiny 10-pin 3mm x 3mm

MLF

–40°C to +125°C.
