Microchip | MIC5159YM6-TR

Micrel’s MIC5159YM6 TR is a precision-voltage regulator controller. Used with an external P-Channel MOSFET, the MIC5159 forms a two-chip low-dropout regulator capable of driving a wide range of output currents.

The MIC5159 operates from an input of 1.65 V to 5.5 V. The low input voltage allows the MIC5159 to operate off of high power 1.8 V rails to generate lower voltages such as 1.5 V. Features of the MIC5159 include enable input and current limit protection. As a µCap design, the MIC5159 is stable with ceramic output capacitors.

The MIC5159 is packaged in the IttyBitty™ SOT-23-6, and is offered in fixed and adjustable output voltages. Junction temperature range of the MIC5159 is from –40°C to +125°C.
