MIC5159

Micrel's MIC5159 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 1.65V to 5.5V. The low input voltage allows the MIC5159 to operate off of high power 1.8V rails to generate lower voltages such as 1.5V.

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.
