12v to 3v voltage regulator circuit.

Because a number of modules for the arduino or pinguino take 3 3 volts it s true some of the arduinos do have a 3 3v voltage regulator and thus a source of 3 3v however that might not have sufficient amperage. To power the circuit you can use a 9v battery but i have used my bench power supply which is set at 9v. The voltage divider is basic and easiest circuit to stepdown any dc supply. Let s take the value of r 2 as 1kω.

Refer to the voltage reference circuit to set the resistance r 1. Better life with high current in the same voltage 1 25v to 30v. Current limiting and thermal shutdown circuit protection provided by ic feature. The cap 10uf tied to the voltage divider is meant to remove ripples from the output for a constant voltage level.

And a higher maximum at 60 volts. Fixing the r2 value as nearest resistor element 200 ohms this will give 3 3v as output from the above circuit. The output voltage can be set from 3 3v to 12v using the potentiometer. And cheap for all the jobs.

Design for an op amp voltage regulator circuit to drive a load of 6v 1 2w from an input supply of 12v with a 2v ripple voltage using a 3v zener diode. You can easily step down any dc supply by just using 2 resistors. The lm1117 3 3 is a low dropout voltage regulator with a dropout of 3 3v 800ma of load current. Output 3 3 v 800 ma regulated low ripple dc voltage.

Output current voltage 0 iout 800ma 4 75v vin 12v. 30v dual adjustable voltage regulator. See below circuits better. In this article we are going to make a simple circuit to stepdown 12v into 3.

Technically the circuit can be designed for a high output current as much as 4a. But due to the limitation of the output diode the circuit is not tested in a full load. Lm338 5a variable regulator. Input 5 to 15 vdc.

99 get it as soon as thu sep 24. I created a simple circuit using the lm317 to output 3 3 volts from a 5v or greater input voltage. Dual power supply 3v 5v 6v 9v 12 15v selects volts easily. So well circuit start voltage at zero voltage.
