Overview

The LD1117S 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 1.2V@(800mA) 15V 75dB@(120Hz) 800mA 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 (Regulators:REG3+1 1ADJ-2OUT-3IN+4OUT, from CERN's library) and its footprint (ICs And Semiconductors SMD:SOT230P700X180-4N, from CERN's library), ready for a KiCad board. 3 are in stock at JLCPCB (part C283466).

Questions

Is there a KiCad symbol and footprint for the LD1117S?

Yes. The symbol is Regulators:REG3+1 1ADJ-2OUT-3IN+4OUT and the footprint ICs And Semiconductors SMD:SOT230P700X180-4N, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LD1117S?

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

Where is the LD1117S datasheet?

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

Where can I order the LD1117S?

JLCPCB lists it as part C283466, with 3 in stock; the sellers' links on this page open their listings.

What can replace the LD1117S?

Parts like it in the library: the LM1117MPX-ADJ by Texas Instruments, the LM1117IMPX-ADJ by Texas Instruments, the LM317EMP by Texas Instruments and the TLV1117CDCY by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
