  • Description

    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).
