General 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 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
μ
Cap 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
