Overview

The LM317LM is a linear Voltage Regulator made by onsemi in a SOIC-8 package with 8 pins. 0.003%Vout 0℃~+125℃@(Tj) 1 1.2V~37V 100mA 40V 65dB@(120Hz) Adjustable Positive SOIC-8 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.

PCBKit's library has its KiCad symbol (Regulators:LM317LM, from CERN's library) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C84381).

Questions

Is there a KiCad symbol and footprint for the LM317LM?

Yes. The symbol is Regulators:LM317LM and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM317LM?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the LM317LM datasheet?

onsemi publishes it: the Datasheet link on this page opens it.

Where can I order the LM317LM?

JLCPCB lists it as part C84381, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM317LM?

Parts like it in the library: the LP2951CM-3.3 by Texas Instruments, the MC78L05ACDX by onsemi and the LTC1763CS8-3.3#TRPBF by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
