Dual Variable Power Supply Schematic. Power supply is mos. We use an lm7812 voltage regulator ic for 12v and lm7912 for 12v.
Transistor variable power supply 1a 0 30v. This circuit is suitable for a preamplifier tone control with op amp circuit. But it still has the same characteristics as a fixed regulated power supply.
Moreover it s equipped with an over load and over current protection features.
Dual polarity variable linear power supply dpv lps disclaimers. Transistor variable power supply 1a 0 30v. This tutorial is for educational purpose only and neither the author nor this website makes no warranty representation or guarantee regarding the information contained herein or any product based on this tutorial or use of any components or circuit design. But it can provide to 1 5 a and gets input voltage of 3v to 40v it is easy to apply and these features have advantages more than regular ic 78xx series a lot.
