Regulator IC LM 317 T in parallel

These regulators are able to withstand short circuit at the output of the source and not so easily destroyed like LM350K or LM338K regulators, the regulator IC used in this circuit using ST manufacturing company and have shown positive result.

The schematic diagram come from circuit: Power supply 4.5 A with 3 LM317 in parallel power supply. Go to that page to read the explanation about above power supply related circuit diagram.

Power supply 4.5 A with 3 LM317 in parallel
This lm317 variable power supply can supply a voltages from 1.2V to 30V with a current 3 amperes, just as the title of this series based on LM317T voltage regulator, the LM317T regulator provide around 1.5 amperes on the heatsink, ...

Low Voltage Regulators with Short Circuit Protection
These Low Voltage regulators with short circuit protection can provide 6, 7.5, and 9 V from an automobile battery supply of 13.5 V nominal, however, they will function just as well if connected to a smoothed dc output from a ...

Electronic crowbar for AC and DC lines
For positive protection of electrical or electronic equipment, use this against excessive supply voltage. Because of incorrect switching, electrical wiring, short circuits, or failure of regulators, an electronic crow-bar circuit can quickly place a short circuit through the power lines, ...

Current Source / Regulator
The Current Source/Regulator circuit powers the load through the regulator's input rather than its output. Since the regulator's output sees constant dummy load R1, it attempts to consume a constant amount of current, regardless of what the voltage across the ...

5V Switch Mode Power Supply using LM2674
In the typical power supply is used in chip LM2674 company National Semiconductor , for many years engaged in manufacturing and designing components for the pulse transformers. LM2674 can be used instead of a chip LM2671 . By choosing different ...
