[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 ...

a simple regulator circuit just using two parallel transistor and potentiometer to make adjustable voltage output. a simple regulator circuit just using two parallel transistor and potentiometer to ...

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 ...

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 ...

The ZXTR2000 family of high-voltage regulators from Diodes Incorporated boosts power-circuit densities through reductions in component count and footprint by monolithically integrating a transistor, ...

Diodes Incorporated has introduced new space-saving package options for its ZXTR2000 series of high-voltage linear regulator transistors designed for 48V circuits in networking, telecom and power-over ...
