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 ...

Many of today’s circuits operate below 1.2 V and the current International Technology Roadmap for Semiconductors (ITRS) projects even lower operating voltages. This requires a compatible, low noise, ...

Linear regulators have limitations with regard to supplying a quiet voltage rail. Alternatively, some very quiet switch-mode power converters, along with some design considerations, can provide a very ...

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 ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

The voltage reference is the last ingredient necessary to build a voltage regulator, otherwise known as the king of power management and power conversion. The most popular voltage references are based ...

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 ...

What is a good solution for generating a tiny dc supply voltage of a few hundred millivolts? The answer is all that is needed is a clean additional positive voltage to hook up to the feedback resistor ...
