MIC61150-10YML TR
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.
