General Description    
 
Micrels   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 礐ap design, the MIC5159 is stable
with ceramic output capacitors.
The MIC5159 is packaged in the IttyBitty
?/DIV>
 SOT-23-6, and
is offered in fixed and adjustable output voltages. Junction
temperature range of the MIC5159 is from 40癈 to
+125癈.
