0-28V, 6-8A Power Supply Circuit using LM317 and 2N3055

Jan 22, 2016 · LM317 is the 3 pin series adjustable voltage regulator. This regulator provides output voltage ranging from 1.2V to 37V at 1.5 amps. This IC is easy to use and requires only two resistors to provide the variable supply. It provides internal current limiting, thermal shut down and it provides more line and load regulation as compared to fixed Adjustable LM317 2-30 Volt Power SupplyThe LM317 is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 32 V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. Furthermore, both line and load regulation are better than standard fixed regulators.

High Current Variable Power Supply using LM317 - Robo

Introduction:This tutorial is in the continuation of AC to DC conversion and rectification. LM317 is used to get regulated power. LM317 is a variable voltage regulator. LM317 Current Boosting Secrets! :4 Steps - InstructablesLM317 is one of the most popular adjustable regulator chips. The output voltage of the regulator can be adjusted from 1.25V to 35V. However, the chip can deliver currents up to 1.5A which is not enough for some power applications. In this article, I will discuss two methods of LM317 current boosting, using power PNP and NPN pass transistors. LM317 Variable Switch Mode Power Supply (SMPS) Jul 08, 2019 · LM317 as Linear Regulator We all know that an LM317 IC is internally designed to work as a linear voltage regulator IC, which has a serious drawback of power dissipation through heating. Moreover such topology also requires the input to be minimum 3V higher than the desired output, adding further restrictions to the given regulator configuration.
