The rise of 3.3V logic and memory components in personal computer systems has created demand for 3.3V power supplies. Several options exist for the computer system designer. One of these options is to ...

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 ...

This circuit is a Mosfet-based linear voltage regulator with a voltage drop of as low as 60mV at 1A. The circuit uses a 15V-0-15V transformer and employs an IRF540 N-channel Mosfet (Q1) to deliver the ...

Today in power electronics, the folks over at Texas Instruments have put together a video covering low-dropout (LDO) linear regulators. For a hacker, power is pretty fundamental, so it behooves us to ...

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 ...

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 ...

The WEA3615LD45G is a voltage feedback amplifier (series – shunt) which active part is comprised of a telescopic cascode amplifier stage, followed by a PMOS pass – device which operates in saturation ...

AP7369Q is a series of 45V input low-drop-out linear regulators from Diodes that can provide up to 150mA to a load. Quiescent current can be as low as 2.1µA and, depending on variant, the output is ...

A synchronous step-down switching regulator has been designed by Linear Technology to deliver 1A on a 100V input with efficiency up to 90%. Burst mode operation is used to keep quiescent current under ...

Step-down (buck) voltage regulators have long been the preferred DC-DC conversion electronic workhorse thanks to their inherently high efficiency. Only in buck mode the current is directed to the ...
