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 ...

Modern system boards include big, current-hungry digital ICs along with a plethora of other lower-current digital and analog circuitry. Such a system board can require as many as five or six power ...

In this article, we focus on two key application-oriented parameters of the linear regulator: Power Supply Ripple Rejection (PSRR) and output noise. These parameters have been discussed before (see ...

An IC with a buck regulator, boost regulator, and a linear charger combine to seamlessly maintain a constant VOUT even if VIN drops out for a short time. The IC can aid solid state drives that ...

Low-dropout (LDO) linear regulators have been widely used in noise-sensitive applications for decades. Nevertheless, noise requirements have become tougher to meet as the latest precision sensors, ...

Diodes has created a quiet low-drop out (LDO) linear regulator for powering ADCs, DACs, VCOs and phase-locked loops. “With up to 90dB PSRR [power supply ripple rejection], and output noise at 8μVrms, ...

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 ...

People have been predicting the demise of low-drop-out linear regulators in cars for many years. Yet low-drop-out (LDO) regulators continue to survive and even thrive because they're cheap and easy to ...

Adding to its LDO+ family, Linear Technology has introduced a 600mA low dropout negative linear regulator featuring low noise, rail to rail operation, precision programmable current limit and a ...

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 ...
