Use full battery juice!

  • Super mini size 11.5×9.5mm, SOT23-6 IC with only three caps
  • Input Voltag 1.8-5V, output 3.3V up to 150mA
  • Constant Frequency Operation at All Loads. Low Noise Constant Frequency (1.2MHz)
  • Automatic Soft-Start Reduces Inrush Current
  • Shutdown Current <1 uA, No load current is 1.77mA.
  • Short-Circuit Protection
  • No Inductors
  • Standard 2.54 pin output, 3.3V-GND-VIN (face to top), can be used as a normal SMD part.

Testing for reference:

  • 1.8V VIN -> 3.3V output
  • 1.5V VIN -> 3.1xV output, still can drive a lot MCUs.

Updated to R2:

  • Added EN enable pin of the chip
  • EN default pull up to high level, connected by jumper VIN.
  • Set EN to low level, can simply connect to battery ground to shut power down, for power saving.


  • 2 AA Cell to 3.3V, tested can also get 3.2x V from a full 1.5V AA battery.
  • USB On-The-Go Devices
  • White LED Driver
  • Handheld Devices

Each purchase is for one board only.
