This Adjustable Voltage Regulator is made by combining a common 78L05 with an integrated audio amplifier of the type TDA2030, an adjustable voltage regulator can be constructed in a very simple manner ...

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.

The circuit was designed to provide a variety of voltages to some electronic equipment with the use of a 12V battery as the power source. The circuit was designed to provide a variety of voltages to ...

Every project needs a power supply. As 3.3volt logic replaces 5volt systems, we’re reaching for the LM317 adjustable voltage regulator, rather than the classic 7805. We’ve found four different ...

In a fashion similar to using stacked Zeners for voltage regulation, this LED circuit cleverly combines voltage reference and voltage indication. Fig 1. This voltage regulator circuit (a) uses green ...
