General Description

The Micrel MIC61150 is a 1.5A output, low input voltage,

single-supply regulator. This regulator operates over a

single input voltage range of 1.1V to 3.6V and offers an

ultra-low dropout less than 200mV over the entire

operating temperature range.

The MIC61150 is designed to drive digital circuits requiring

low voltages at high currents such as DSPs, FPGAs,

microcontrollers, etc. The regulator is available as a 1.0V

fixed-output voltage option or as an adjustable-output

voltage option.

The MIC61150 is stable with a 22µF, low-ESR ceramic

output capacitor, and includes protection features such as

thermal shutdown, current limiting and logic enable.

The MIC61150 is offered in two different packages: a low-

profile, leadless 10-pin 3mm x 3mm MLF

ePad MSOP. The MIC61150 has an operating junction

temperature range of −40°C to +125°C.
