MIC69302WR [Microchip]

The MIC69301/2/3 is the 3A output current member of the MIC69xxx family of high-current, low-voltage regulators, which support currents of 1A, 1.5A, 3A, and 5A. This family operates from a single low voltage supply, yet offers high precision and ultra-low dropout of 500mV under worst case conditions.

The MIC69301/2/3 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. The adjustable version can support output voltages down to 0.5V.

The µCap design of the MIC69301/2/3 is optimized for stability with low value, low-ESR ceramic output capacitors.

Features of the MIC69301/2/3 include thermal shutdown and current limit protection. Logic-enable and error flag pins are also available.

The MIC69301/2/3 is offered in TO-263, S-PAK and the ePad SOIC-8 packages. All packages have an operating temperature range of -40°C to +125°C.
