Lm317 Power Supply. It can supply greater than 1 5 a at the output. The heart of this power supply is an lm317 voltage regulator ic.
The lm317 ic has many features such as current limiting thermal protection and safe operating area protection. 0 60 volt dc variable power supply circuits using lm317 lm337. The lm317 or lm117 series of adjustable 3 terminal positive voltage regulators is capable of supplying in excess of 1 5a over a 1 2v to the 37v output range and has many special features that i like are.
It can also provide a float function for high voltage uses.
Although the voltage regulator lm317 protects the circuit from overheating and overload the fuses f1 and f2 are used to protect the power supply circuit. Although the voltage regulator lm317 protects the circuit from overheating and overload the fuses f1 and f2 are used to protect the power supply circuit. The lm317 device 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 37 v. In this project i have designed a simple adjustable voltage dc power supply using the lm317 ic with an lm317 power supply circuit diagram.
