Part Number: LM317-N Hi team,
My customer is considering to use LM317EMP/NOPB. I think that this device allow ceramic capacitor. Is my understanding correct?
Cin : 1uF Ceramic capacitor
Cout : 4.7uF Ceramic capacitor
Vin : 12V
Vout : 7.5V (R1…
Other Parts Discussed in Thread: LM317-N , TPA6120A2 , TPS7A33 24V input, two LM317-N can output -12V？
I want to drive the earphone with tpa6120a2, its power supply needs =-12V,
So, is there a reference circuit?
Part Number: LM317-N Other Parts Discussed in Thread: LM317 Can someone help me to get the updated 197 SVHC reach statement for the texas instrument component LM317T/NOPB??
In advance thank you for your help and support.
Best Regards.

According to the datasheet of LM317-N (P.14) of 8.4.2 Protection Diodes, it says, for output capacitors…
Other Parts Discussed in Thread: LM317-N Hi, When I using the LDO product filter, The noise of LM317-N shows as 35 uVrms only. ..... I have no idea if a 40yo device has 35 uVrms performance, what does "ultra low noise" really mean? (ps. TPS78630 has 48uVrms…
Part Number: LM317A-337N-EVM Other Parts Discussed in Thread: LM317A , LM317-N Tool/software: Hello,
Could you please help me for understand the use of the fromula VOUT+ = VREF (1 + R3/R1) + (IADJ × R3). Indeed this formula is not related with VIN…
Hi OMG,
The layout looks fine.
Here's what I'm thinking. The junction temperature for the LM317-N, from your measurement, is estimated to be 76C + 2W * 10.4C/W = 97C, and if your board was similar in thermal performance to the JEDEC High-k board…
Hello Shotaro,
1. LM317 is a really old device so datasheet requirements might have been different at that time, therefore, detailed information is not included. The current limit characteristics can be found on the Electrical Characteristics table…
Hi Emma,
I looked at the different datasheets for the LM317.
Here is the dropout from the LM317L-N (100mA)
And here it is for the LM317M (500mA version)
And here it is for the LM317-N
There is some variation, but we can see that…
