The voltage regulator is built around the MA723 integrated circuit and is intended for regulation and stabilization of DC voltage. The input voltage must be rectified and filtered within the range of 28 to 37 V DC. The output voltage is smoothly adjustable from 2 to 25 V DC using a trimmer potentiometer.
The circuit includes current protection that activates at approximately 2 A. The current limit threshold can be adjusted by changing the value of resistor R1.
The external power transistor must be mounted on a suitable heatsink to ensure proper heat dissipation.
The printed circuit board dimensions are 48 x 31 mm.
