In Figure 1, the 5V linear regulator (U1) delivers as much as 150mA of load current when operating by itself. Operating with the external pass transistor shown (Q1), the circuit maintains 5V ...

This article presents linear regulators and the computation of its efficiency. It also describes the advantages and other properties of a linear regulator, as well as the low drop out (LDO) regulator, ...

Diodes Incorporated has introduced new space-saving package options for its ZXTR2000 series of high-voltage linear regulator transistors designed for 48V circuits in networking, telecom and power-over ...

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 output ripple of a standard isolated dc-dc converter is between 0.5% and 1% of its nominal output voltage. For applications requiring a lower output ripple, linear voltage regulators can reduce a ...

[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 ...

PLANO, Texas--(BUSINESS WIRE)-- Diodes Incorporated (NAS: DIOD) , a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and ...

MJE1123, once from Motorola and now from New Jersey Semi-conductor Products, is a rather specialised transistor. It is a 40V 4A power pnp with high gain and good saturation (200mV max at 1A). The ...

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 ...

The ZXTR2000 family of high voltage regulators from Diodes is designed to boost power circuit densities through reductions in component count and footprint. It does this by monolithically integrating ...

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 ...
