Overview

The LD1117SC-R is a voltage Regulators Linear, Low Drop Out (LDO) Regulator made by STMicroelectronics in a SOT-223 package with 4 pins. 0.003%Vout 0℃~+125℃@(Ta) 1 1.25V~15V 1.3V@(800mA) 15V 5mA 75dB@(120Hz) 800mA Fixed Over Current Protection Positive SOT-223 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 (Package_TO_SOT_SMD:SOT-223, from KiCad's library), ready for a KiCad board. 3 are in stock at JLCPCB (part C970562). 2 open-source boards in 2 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the LD1117SC-R?

Yes. The symbol is Celestial_Power_Linear_VReg:ST LD1117 and the footprint Package_TO_SOT_SMD:SOT-223, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LD1117SC-R?

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

Where is the LD1117SC-R datasheet?

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

Where can I order the LD1117SC-R?

JLCPCB lists it as part C970562, with 3 in stock; the sellers' links on this page open their listings.

What can replace the LD1117SC-R?

Parts like it in the library: the NCP1117ST33 by onsemi, the AZ1117H-3.3TRE1 by Diodes Incorporated, the LD1117AG-33-AA3-A-R by UTC and the AZ1117CH-3.3TRG1 by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LD1117SC-R?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
