Description

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 it 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 currentlimit protection. As a Cap design, it 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 it is from 40 to +125.
