Voltage Regulator Circuit Voltage Regulator Circuits

Voltage Regulator, as the name suggests, is a circuit that is used to regulate the voltage. Regulated voltage is a smooth supply of voltage, free from any noise or disturbance. The output from the voltage regulator is independent of load current, temperature, and AC line variation.  Engineers can create reliable power supply systems with the aid of these voltage…

LM317 Variable Voltage Regulator Circuit LM317 Variable Voltage Regulator Circuit

Whenever we need a constant and specific value of voltage without fluctuation we use voltage regulator IC. They provide a fixed regulated power supply. We have 78XX (7805, 7806, 7812 etc) series voltage regulators for positive power supply and 79XX for negative power supply. But what if need to vary the power supply voltage, so here we have Variable Voltage Regulator IC…

Arduino Variable Power Supply Variable Power Supply By Arduino Uno

In this tutorial, we will develop a 5V variable voltage source from Arduino Uno. For that, we are going to use ADC (Analog to Digital Conversion) and PWM (Pulse Width Modulation) features.

Some digital electronic modules, like accelerometers, work on a voltage of 3.3V, and some work on 2.2V. Some even work on lower voltages. With this, we cannot get…
