Overview

The LM140LAH-12 is a voltage Regulators Linear, Low Drop Out (LDO) Regulator made by Texas Instruments in a TO-39-3 package with 3 pins. -55℃~+125℃ 1 100mA 12V 2V@(1A) 35V 3mA 72dB@(120Hz) Fixed Positive TO-39-3 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.

PCBKit's library has its KiCad symbol (Pinmap_Generic:Regulator_Linear_1IN_2OUT_3GND, from PCBKit's generic symbols) and its footprint (Package_TO_SOT_THT:TO-39-3, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2868004).

Questions

Is there a KiCad symbol and footprint for the LM140LAH-12?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2OUT_3GND and the footprint Package_TO_SOT_THT:TO-39-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM140LAH-12?

TO-39-3, with 3 pins. Its footprint is drawn on this page.

Where is the LM140LAH-12 datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM140LAH-12?

JLCPCB lists it as part C2868004, with 0 in stock; the sellers' links on this page open their listings.

What can replace the LM140LAH-12?

Parts like it in the library: the 78L12 by UMW, the L78L12ABU by STMicroelectronics, the 78L12G-AB3-R by UTC and the CJ7812 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
