In Seemingly Simple Circuits: The TL431 Voltage Regulator, Part 2, we looked at how voltage gain of the TL431 is measured. Now we plunge deeper in, to look at closed-loop output resistance, derive ...

We submerge somewhat deeper into analysis of the seemingly simple TL431 voltage reference with transconductance amplifier to find that some useful design parameters are missing from the manufacturer ...

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 ...

Here, Doug Mercer and Antoniu Miclaus of Analog Devices explore Zener diode regulators. A voltage regulator is a circuit used to maintain a constant output voltage at a load independent of changes in ...

Abstract: A very low drop voltage regulator that uses an NMOS output transistor, a start-up circuit and two voltage comparators, designed in a 0.12 /spl mu/m CMOS technology, is presented. By means of ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost any job in ...
