Lm317 Schaltung Poti. The internal reference voltage of the lm317 is 1 25v. This voltage needs to be dropped across the shunt resistor before the lm317 starts limiting.
The device features a typical line. Lm117 lm317 n snvs774q may 2004 revised june 2020 lm117 lm317 n wide temperature three pin adjustable regulator 1 1 features 1 for a newer drop in alternative see the lm317 typ. The lm317 is an adjustable 3 terminal positive voltage regulator capable of supplying in excess of 1 5 a over an output voltage range of 1 2 v to 37 volts.
The internal reference voltage of the lm317 is 1 25v.
Lm317 adjustable regulator datasheet specifications. You need to connect the 240 ohm resistor between out and v adj then connect the pot between v adj and ground. It requires only two external resistors to set the output voltage. 0 01 v line regulation 1 5 a output current adjustable output down to 1 25 v current limit constant with.
