Overview

The LD1117AS is a voltage Regulators Linear, Low Drop Out (LDO) Regulator made by STMicroelectronics in a SOT-223-3 package with 4 pins. 0℃~+125℃@(Tj) 1 1.25V~15V 1.3V@(1A) 100uV 10V 1A 5mA 80dB@(120Hz) Adjustable Over Current Protection、Over Temperature Protection Positive SOT-223-3 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.

PCBKit's library has its KiCad symbol (Celestial_Power_Linear_VReg:ST LD1117, from Altium's library) and its footprint (EasyEDA_Cloud:SOT-223-3_L6.7-W3.7-P2.30-LS7.0-BR, from EasyEDA), ready for a KiCad board. 2,535 are in stock at JLCPCB (part C283464). 3 open-source boards in 3 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the LD1117AS?

Yes. The symbol is Celestial_Power_Linear_VReg:ST LD1117 and the footprint EasyEDA_Cloud:SOT-223-3_L6.7-W3.7-P2.30-LS7.0-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LD1117AS?

SOT-223-3, with 4 pins. Its footprint is drawn on this page.

Where is the LD1117AS datasheet?

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

Where can I order the LD1117AS?

JLCPCB lists it as part C283464, with 2,535 in stock; the sellers' links on this page open their listings.

What can replace the LD1117AS?

Parts like it in the library: the NCV1117ST12 by onsemi, the JY1117E50AX by Shenzhen JingYang, the LD1117AS18 by STMicroelectronics and the ICW1117A50S3G by ICW. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LD1117AS?

3 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
