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 ...

The importance of low Iq with linear regulators and LDOs. A look at low-Iq voltage supervisors in portable electronics. Battery-voltage supervisors in the IoT. In my article “What is the Essence of ...

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 ...

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 ...

With so much analog-circuit design being done by automated tools and circuit-performance analysis done with tools such as Spice, it may seem anachronistic to actually go through a basic circuit 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 ...

[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 ...

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 ...
