Special Features of AK-252
This Breadboard power supply module is designed to get regulated voltage
from any external power source, either from the DC barrel jack or terminal
block. The best part of this board is, you can use the power supply at three
different modes of voltages- 3.3V,5V and at variable voltages from 1.25V to
20V. The end user can select the voltage using 3-way switch.
Features:
• Used MIC2941 which has low voltage dropout (40mV) comparted to
LM317(1.25V).
• 2.1mm DC jack and terminal connector for voltage inputs.
• Two indicator LEDs, Red for input power and green for output power.
• Short circuit and over heating protection.
• Input diode to protect circuitry from negative voltages or AC power
supplies
• Onboard potentiometer for adjusting voltage from 1.25V to 20V with in
0.5V of the input voltage.
