3v Voltage Regulator Circuit

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.

3v voltage regulator circuit.

Fixing the r2 value as nearest resistor element 200 ohms this will give 3 3v as output from the above 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. The lm1117 3 3 is a low dropout voltage regulator with a dropout of 3 3v 800ma of load current. 99 get it as soon as thu sep 24.

6v op amp voltage regulator. This project will provide 3 3 v 800 ma dc regulated supply. I created a simple circuit using the lm317 to output 3 3 volts from a 5v or greater input voltage. The same low cost printed circuit board can be used for the voltage of your choice and gerber files are provided later in this article.

This project is a 3 3v voltage regulator. 3 3v 1 25 1 r2 120 r2 196 ohms. The project is based on the lm1117 low dropout linear regulator. This is the basic ld1117v33 voltage regulator a low drop positive regulator with a 3 3v fixed output voltage.

Input 5 to 15 vdc. Free shipping on your first order shipped by amazon. Get it as soon as tue sep 22. The cap 10uf tied to the voltage divider is meant to remove ripples from the output for a constant voltage level.

Linear ics normally a step down voltage from a higher voltage source is obtained by using a linear ic such as a 78xx series voltage regulator ic or a buck converter. Let s take the value of r 2 as 1kω. This fixed regulator provides a great amount of stability and protection for your project and with its on chip trimming this regulator is able to reach an output voltage tolerance within 1.
