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 ...

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 ...

What do you do when your maximum input voltage = 90V and /or linear regulator has unreasonable power dissipation? First, here are a few specifications to digest for a 24V @ 70°C ambient application: ...

Semiconductor memory, card readers, microprocessors, disk drives, piezoelectric devices, and digital systems create transient loads that voltage regulators must service. Ideally, regulator output ...

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 ...

Before a circuit designer decides on a particular power supply, he or she will first want to test it carefully. The data sheet for a switching regulator IC provides valuable information on how the ...

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 ...
