Description
Once assembled this kit provides a very low dropout adjustable power supply. The board can supply 3.3VDC , 5VDC, and an adjustable 1.25 – 19.5VDC (when a 20V input voltage is used).
Features
- MIC2941 regulator has guaranteed 1.25A output
- Short circuit and overheating protection
- 2.1mm DC jack and terminal connector for voltage inputs
- Output selection switch to select from 3.3v, 5v and adjustable
- On/Off switch for entire board
- Low dropout, only 40mV – 400mV compared to 1.25V – 2.0V for LM317
- Input diode to protect circuitry from negative voltages or AC power supplies
- Two indicator LEDs for high and low voltages
- Onboard potentiometer for adjusting voltage from 1.25V up to within 0.5V of the input voltage. (20V max)
- Heat sink included
