There are many circuits for low voltage regulators. For higher voltages, such as supplies for valve circuits, the situation is different. That’s why we decided to design this simple regulator that can ...

People often forget that many voltage regulator ICs have an upper limit (usually 35 V) on the input voltage they can handle. That applies primarily to types with a fixed output voltage. Adjustable ...

This file type includes high-resolution graphics and schematics when applicable. A common project requirement is to have an adjustable voltage regulator programmed to deliver a specific dc output.

Low dropout (LDO) regulators play a very important role in the power management of an integrated circuit. As a result, mindful designing and selection of LDO circuits become crucial. This article ...

Nerd Ralph loves cheap and dirty hacks, and for that we applaud him. His latest endeavor is a LiFePO4 battery charger that he made out of parts he had on hand for under $0.50 US. (Although we think he ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

Fig 1. This voltage regulator circuit (a) uses green LEDs as both the stabilization elements and as the voltage indicators at the front-panel switch (b). Fig 2. The addition of resistor R4 to the ...

In this guide, we explain the Voltage Regulator Module (VRM) in simple terms for everyone to understand. For the optimal performance and longevity of electronics, it is important to maintain stable ...
