Lm7805 Circuit 12v To 5v. See 7805 pinout below. The circuit is using two assorted fixed voltage regulator ics.
12v To 5v Converter Step Down Dc Regulator In Many Ways To Do Electronic Circuit Projects Electronic Schematics Electronics Basics from www.pinterest.com
It is used for 10ma to 1 amp medium current to the high current applicational circuits. Pls send me specifications and parametrs required for design of power supply using ic 7805 with fixed voltage 5v and giving current range 0 5a seetharaman 9 years ago hi kalyani you use the technique used in our earlier circuit for 12 volts. 7805 regulator 5v module.
So what s happening is that on the input side you give the 12v dc input and the ic regulates that voltage and gives an output of ideally 5v 4 8v to 5 2v as per its datasheet.
This circuit of the power supply is a dual power circuit. Which is a simple circuit using ic 7805 to the fixed regulator 5 volts and tip41 npn power transistor to increase current up to 2a.
