Switching regulators have delivered such convenience and efficiency compared to their linear siblings, that it’s now becoming rare to see an old-style three-terminal regulator. Modern designs have ...

A recent Design Idea, “Three discretes suffice to interface PWM to switching regulators,” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...

Nearly every new design tries to add functionality while using less power. Recent products from Infineon Technologies, National Semiconductor, Ricoh Europe BV, and Dialog Semiconductor all seek to ...

Developed as a three-terminal shunt regulator, the popular and multiple-sourced TL431 IC offers designers many intriguing possibilities beyond its intended application. Internally, the TL431 comprises ...

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.

Delivering many improved major specs over traditional LM324 op-amps, but with rail-to-rail inputs and outputs, STMicroelectronics has introduced a 6MHz all-rounder op-amp family that will operate from ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...
