A constant current circuit can also be used as a current limiter.

Lm317 adjustable current limiter circuit.

The input supply source is connected across the vin and ground of the upper current regulator circuit the output from this stage goes to the input of the lower lm317 variable voltage regulator stage. Also see lm317 high power constant current source circuit. A constant current source ccs in electronics is a device circuit that produces a constant value of current regardless of source voltage or load resistance. 3d biometrics hyperspectral imaging.

It can also provide float operation for high voltage application. Precision current limiter schematic for lm317 lm338 lm350. This circuit addresses that problem. The lm317 ic helps in current limiting thermal overload protection and safe operating area protection.

Constant current portion of the lm317 based power supply with current limiting. 1 amp current regulator schematic for lm317 lm338 lm350. In most of the applications due to irregular loads the output voltage produced has fluctuations in it which can lead to damaging loads. Lm317 is a positive voltage regulator with an adjustable voltage range from 1 25 v to 37 v.

It can supply greater than 1 5 a at the output. It s having a typical line and load regulation of 0 1. Lm317 3 terminal adjustable regulator 1 1 features 1 output voltage range adjustable from 1 25 v to 37 v output current greater than 1 5 a internal short circuit current limiting thermal overload protection output safe area compensation 2 applications atca solutions dlp. If we disconnect the adjustable terminal still lm317 will helpful in overload protection.

Lm317 can also be used to design various other circuits like 0 v to 30 v regulator circuit adjustable regulator circuit with improved ripple rejection precision current limiter circuit tracking pre regulator circuit 1 25 v to 20 v regulator circuit with minimum program current adjustable multiple on card regulators with single control. To be precise the upper lm317 forms the current regulator stage while the lower acts like a voltage controller stage.
