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 lowprofile, 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 temperature 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
