5v dc regulated phone charger circuit

A 5V to 2.5V voltage regulator circuit is designed for use in computer motherboards. At its core, this circuit utilizes the RT9202 power management chip. The RT9202 functions as a switching pulse generating circuit, which, upon startup, converts a 5V...

12-16V-converter

Many devices operate from a car's 12-V electrical system. Some require 12 V, while others need a lower voltage. An automobile battery's output can vary from 12 to 13.8 V under normal circumstances. The load requirements of the device may...

10 Amp 13.8 Volt Power Supply

Sometimes amateurs like to home-brew their power supplies instead of purchasing one off the shelf at any of the major ham radio retail dealers. The advantage to rolling your own power supply is that it teaches us how they work...

Regulator Combination Circuits

There are a number of ways to obtain the low voltages required to run small projects from the wall power outlet. The simplest way is to buy a factory-built molded supply which is designed to plug directly into the wall...

Automobile-voltage-regulator

A monolithic 555-type timer serves as the core component of this straightforward automobile voltage regulator. When the timer is inactive, resulting in a low output at pin 3, the power Darlington transistor pair remains off. If the battery voltage drops...
