It couldn’t be simpler but you have to admit that a small adjustable portable power supply like this one will be really handy. The main part of the PSU is an LM317 linear voltage regulator which we’re ...

Perhaps the simplest way to regulate a DC voltage is using a voltage divider and/or an active device like a Zener diode. Besides simplicity, they have the additional advantage of not being ...

This circuit uses a step-up switch-mode regulator, which is usually used to produce a positive supply, to generate a regulated negative output voltage. The device used here is the MIC4680 from Micrel, ...

To maximize system efficiency, buck regulators minimize power loss in the switching MOSFETs, inductor, capacitors, controller, and printed circuit board traces. Fairchild’s TinyBuck® family of ...

What is the function of a switching voltage regulator IC? A switching voltage regulator accepts a dc input voltage and converts it to a switched voltage that can extend into the MHz region. Then, it ...

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...
