Datasheet of my LM317t : https://www.electro-tech-online.com/custompdfs/2012/10/LM317.pdf
I have a power supply 30VDC, 5A. I want to use LM317 to get an output of 13.75V by using the following resistor
Vout to Adj - 1KΩ
Adj to ground - 10KΩ
After connecting the resistors i get 30V output. There is no change in V. What am i doing wrong?
----------------------------------------------------------------------
When i finished writing the above i felt like double checking my circuit, then i found out that i was using wrong resistor. After fixing the resistor it works great its V is very accurate and regulated.
Thank you for reading. Read resistor marking carefully. Some time i wonder why didnt they just printed the value in number.
Regards
