Part Number: LM317 Tool/software: HI,
We're using an LM317 as a current regulator (45mA) to drive a current loop communications circuit for petrol pumps. The current in the loop is simply turned on and off with optocouplers and transistors in the…
Part Number: LM317 Tool/software: Need to have a reference circuit for using LM317 as constant current of 1mA.
application - will be use to sense temperature from PT100 sensor. (3 wire)
Voltage used is AA battery - 3V.
Part Number: LM317 Tool/software: Hi team,
My customer designed LM317 in their system but seems thermal problem, so they consider to use 3pcs devices to share thermal.
Can they just do parallel design? Or any circuit we need to modify?
Part Number: LM317 Tool/software: I understand the normal equation will be below.
However we saw on the specification this formula adding R3 and -10V in the mix.
May I know when we will use both formula and what is the model behind the second equation…
Part Number: LM317 Tool/software: dears,
My customer is seeking for 35V vin, 1.5A output LDO, LM317KTTR may meet these requirement, but their environment temp range is -40~125 degree C? could LM317KTTR may be able to support this case?
if any other TO-263…

Part Number: LM317 Tool/software: Hello,
I'm trying out an LM317 as a current limiter (approx. 1A max) for a purely resistive load. I've set up the design as per the datasheet (see schematic attached here).
My input voltage is +36Vdc from a…
Hi Aki,
Yes, you typically want an LDO here. LDO = Low Dropout, which is a subclass of the overall family of linear regulators. The LM317 is a linear regulator (but not low dropout). Almost all new linear regulators being designed are LDO's. I'll…
Hello Jade,
I will be taking over to help facilitate questions on this thread.
Could you please update me on what still needs to be done to answer your questions?
Thank you,
Hannah
