Low Input Voltage, Single-Supply
High-Current LDO
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® and a 10-pin
ePad MSOP. The MIC61150 has an operating junction
temperature range of 40°C to +125°C.
Single VIN rail: 1.1V to 3.6V
Output voltage accuracy: ±2.5% over temperature
Typical dropout of 75mV at room temperature
– Maximum dropout of 200mV at full load over
COUT as low as 22µF (ceramic capacitor)
Output voltage adjustable down to 0.5V
Soft-start control via external capacitor
Excellent line and load regulation
Logic controlled shutdown
Thermal-shutdown and current-limit protection
10-pin 3mm × 3mm MLF® package
10-pin ePad MSOP package
Junction temperature range from 40°C to +125°C
