Electronic systems often require multiple voltages to power the various internal circuits. Non-isolated regulators are a common and easy way to convert one voltage to another. Regulators typically ...

A new breed of switchers solves the objections to using switch-mode converters and paves the way for replacement of LDOs The combination of today’s energy prices and an ethical obligation are driving ...

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 ...

Using a “trick,” a switching or linear regulator can generate lower voltages than the feedback voltage. It requires another positive supply voltage connected to the resistive divider to adjust the ...

Feedback-control schemes for linear systems have been around since at least the 17 th century, regulating pressure and distance between millstones and then, famously, to control James Watt’s steam ...

Monolithic, or integrated, linear voltage regulators make it possible to build a stable power supply with a small number of parts, saving both time and space. Additionally, a lot of the modern devices ...

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 ...

Low dropout (LDO) regulators play a very important role in the power management of an integrated circuit. As a result, mindful designing and selection of LDO circuits become crucial. This article ...
