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 ...

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, ...

Editor's note: Designers at all levels of power management design will find this application article both educational for those not very familiar with these basic concepts as well as an excellent ...

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 ...

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 ...

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 ...
