## Description

Power up your project with this 3.3 V LDO regulator.

Designed to create a continuous supply for the Pico, while still allowing Makers to use the USB to program and test their projects. The diode prevents the back-charging through from the USB - allowing for different battery chemistries to be used: Alkaline, LiPo, NiMh, ect.

Simply connect your battery to GND and IN. and the device you are looking to power to GND and 3.3V.

Includes 3-pin straight and 3-pin right-angle headers.

### Specifications

- Maximum current: 1 A
- Maximum voltage: 12 V (Linear regulators heat up as the difference in voltage increase, try to stay as close to 3.3V as possible to reduce loss)
