OVERVIEW
INTRODUCTION
The regulated power supply accepts unregulated inputs from 9V to 15V AC or DC and gives
regulated output of 3.3V, 5V and 12V suitable for projects which needs precise voltage to
work. The input can come from step down transformer. Since board has Diode Bridge input
polarity does not matter. All outputs are brought to screw terminal. There is also an unregulated
output voltage to drive high current loads like relays and motors.
