MIC61150
Low Input Voltage, Single-Supply
High-Current LDO
General Description
Features
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
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

Pin Function
Input Voltage.
Ground: Input and output return pin. Connect GND near the point-of-load.
Enable: Active-high control input that allows turn-on/-off of the LDO.
No external function. Tie to ground.
Internal Charge Pump Circuit Output: Connect a 0.1µF to 1µF capacitor from CP pin to GND to
control the ramp rate of the output.
Adjustable Regulator Feedback Input: Connect to the resistor voltage divider network that is
placed from OUT pin to GND pin in order to set the output voltage. See Typical Applications
Circuit.
Fixed-Output Voltage Sense Input: Connect the SENSE pin of the fixed output option at the point-
of-load to accurately monitor the output voltage level.
Regulator Output: The output voltage is set by the resistor divider connected from VOUT to GND
(with the divided connection tied to FB). A 22µF ceramic capacitor with low ESR is required to
maintain stability. See Applications Information.
Connect to GND.
