3v power supply circuit diagram. Lm317 linear power supply regulator selector 15v3v45v5v6v9v 15a. And higher maximun at 60 volts. This 13v power supply can be used as replacement for the 13v mercury cell in any circuit. Posted by circuit wiring in converter circuits.
We decided to design simple power supply circuits that can output 33v. This circuit and wiring diagram. You still can obtain 33v from the above circuit. When the input 5v is given to the circuit the voltage drop across zener diode d1 will be around 2vthe diode d2 will drop a 07 v from the 2v volt and the remaining 13v will be available at the output.
In case if you have got the adjustable version of the ic by mistake not to worry. The figure below shows a very useful project schematic of a regulated 3v 1a dc power supply circuit. Dc 1 3v to 22v power supply circuit diagram has been viewed 564 times which last viewed at 2019 01 13 190952 and has been downloaded 1 times which last downloaded at 2016 02 09 142605 added by kayla on 20 mar 2014. 33v power supply circuit using adjustable version of ld1117.
So well circuit start voltage at zero voltage. See this circuits better. Regulated 33v using lm317 among the power supplies presented here this is a well regulated type that can deliver up to 15a current from a wide range of input voltage of 5v to 25v dc. Neon flasher circuit diagram.
The dc 1 3v to 22v power supply circuit diagram can be download for free. You can use as as battery so saving. This is lm317 voltage selector power supply projects can select output 15v3v45v5v6v9v at 15a current. 0 60 volt dc variable power supply using lm317lm337.
The circuit is using only handful of parts and can be made in very short time if all parts are available with. The circuit has two parts. Steps up the 3v battery supply to around 95v or so to drive a neon with ease. Many electronics circuits and projects for learning in simple ways.
Ic1 operating as step up converter. The circuit can be used to operate wide variety of 3 volt equipments.
