LM317LM Replacement with low FB reference current

Nov 04, 2014 3 Replies

Hi



The LM317LM has up to 100uA of current into (or out) of the FB/ADJ pin.



I would like to reduce the power consumption of the low resistance ladder normally used to avoid leakage current errors



Does a part exist that has optimized performance of the LM317?



(we are using the SOIC8 part)



Cheers



Klaus


Nevermind, the LM317 has minimum outout current of 2.5mA, so I need to find a new part, that's just doesn't cut it for our design

Cheers

If you don't need a pin compatible replacement you could look at the

Yes, there's plenty of part out there. I needed a pin for pin replaceable p art

Thanks
