Description

This kit is for making your own breadboard-friendly very low dropout adjustable power supply. A good power supply is essential to electronic projects. While there are many existing designs for adjustable power supplies, this one makes improvements that make it more useful for hobby designs

MIC2941 regulator has guaranteed 1.25A output
Low dropout, only 40mV – 400mV compared to 1.25V – 2.0V for LM317. This means you can use a wider range of output voltages including generating 3.3V from as low as 3.7V (such as 3 AA’s or a lithium ion battery)!
Short circuit and overheating protection
Input diode to protect circuitry from negative voltages or AC power supplies.
2.1mm DC jack and terminal connector for voltage inputs
Two indicator LEDs for high and low voltages
Output selection switch to select from 3.3v, 5v and Adjustable (also has a breakout for the voltage you’re powering the boad with)
Onboard potentiometer for adjusting voltage from 1.25V up to within 0.5V of the input voltage. (20V max)
On/Off switch for entire board
Heat sink included

Project kit comes as components to be soldered to the included PCB. It’s not a difficult project, about 30-45 minutes with a soldering iron. Even beginners can make it! You’ll need a soldering iron, solder, diagonal cutters and a PCB holder such as a helping hand tool. Breadboard and battery clip or DC power supply is not included, you can use any DC power supply with 2.1mm plug (we have a nice one in the shop).
