This is a 0-60V, Dual Variable power supply circuit using LM317 and LM337 at 1.5A current so can builds to easy with PCB layout, adjustable voltage VR1,VR2
Hi, we all know that the LM317/LM337 are certainly not bad, at least better than 78XX and 79XX. I have the those three legged regulators in my DAC (set to 15V), with quite little space around. Audiophonics have this...
LM317 with heat sink The LM317 is an adjustable positive linear voltage regulator. It was designed by Bob Dobkin in 1976 while he worked at National Semiconductor. [1] The LM337 is the negative complement to the LM317, which regulates voltages below a reference. It was designed by Bob Pease, who also worked for National Semiconductor. [1]
3 Description The LM317 is an adjustable three-pin, positive-voltage regulator capable of supplying more than 1.5A over an output voltage range of 1.25V to 37V. The device requires only two external resistors to set the output voltage. The device features a typical line regulation of 0.01% and typical load regulation of 0.1%. The LM317 includes current limiting, thermal overload protection ...
LM317 is a positive voltage regulator and LM337 is the negative compliment voltage regulator IC of LM317. The LM317 IC is a 3-terminal voltage regulator that is designed to supply in excess of 1.5 Amps of a DC output voltage range of (1.2-30) Volts.
The LM317/LM337 symmetrical power supply circuit is an electronic setup for meeting the voltage requirements of electronic circuits. By Simon Munyua Mugo.
Note that the LM317 (Figure 1) is a positive output adjustable regulator. The material in this post is directly applicable to the complementary LM337 negative voltage regulator. Canonical Article: What are jellybean electronic components?
The circuit uses two voltage regulators, the LM317 and LM337, to provide positive and negative voltages, respectively. The circuit is easy to assemble and can be used to power circuits that require positive and negative voltages. How to assemble a dual power supply circuit with LM317 and LM337.
The positive voltage can be regulated and varied using the LM317 IC and the negative voltage can be regulated using LM337 or the LM137 IC. We will also need a center-tapped transformer to get both positive and negative voltages. Figure 7: Dual voltage power supply using two variable voltage regulators
You can add the VR1 in adj pin of the IC1-LM317 and IC2- LM337 look like to Best DC power supply 3Amp to adjust 1.2V-20V & 3V-6V-9V-12V OR 0-60 volt DC variable power supply using LM317&LM337 : So well circuit, start voltage at zero voltage! and higher maximun at 60 volts. The circuit above list may be unnecessary for you. Because large.
