Overview

The LM317T is a voltage Regulators Linear, Low Drop Out (LDO) Regulator made by STMicroelectronics in a TO-220AB-3 package with 3 pins. 0.003%Vout 0℃~+125℃@(Tj) 1 1.2V~37V 1.5A 40V 80dB@(120Hz) Adjustable Over Current Protection、Thermal shutdown Positive TO-220AB-3 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.

PCBKit's library has its KiCad symbol (dk_PMIC-Voltage-Regulators-Linear:LM317T488_Obsolete, from Digikey) and its footprint (digikey-footprints:TO-220-3, from Digikey), ready for a KiCad board. 1,709 are in stock at JLCPCB (part C361026).

Questions

Is there a KiCad symbol and footprint for the LM317T?

Yes. The symbol is dk_PMIC-Voltage-Regulators-Linear:LM317T488_Obsolete and the footprint digikey-footprints:TO-220-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM317T?

TO-220AB-3, with 3 pins. Its footprint is drawn on this page.

Where is the LM317T datasheet?

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

Where can I order the LM317T?

JLCPCB lists it as part C361026, with 1,709 in stock; the sellers' links on this page open their listings.

What can replace the LM317T?

Parts like it in the library: the L7805CV by STMicroelectronics, the L7805CV-DG by STMicroelectronics, the L7805CV(XBLW) by XBLW and the LM317T by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
