Overview

The LDL212DR is a voltage Regulators Linear, Low Drop Out (LDO) Regulator made by STMicroelectronics in a SOIC-8 package with 8 pins. -40℃~+125℃@(Tj) 1 1.18V~17.4V 1.2A 18V 350mV@(1.2A) 380uA 50dB@(100kHz) 60uVrms Adjustable Over Current Protection、Enable Positive SOIC-8 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.

PCBKit's library has its KiCad symbol (ldl212dr:LDL212DR, from Agg-kicad) and its footprint (Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, from KiCad's library), ready for a KiCad board. 148 are in stock at JLCPCB (part C136153). 5 open-source boards in 5 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the LDL212DR?

Yes. The symbol is ldl212dr:LDL212DR and the footprint Package_SO:SOIC-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LDL212DR?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the LDL212DR datasheet?

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

Where can I order the LDL212DR?

JLCPCB lists it as part C136153, with 148 in stock; the sellers' links on this page open their listings.

What can replace the LDL212DR?

Parts like it in the library: the GM12041ARDZ-R7 by GONGMOSEMI, the LT1963AES8#TRPBF by Analog Devices, the LT1963AES8-3.3#TRPBF by Analog Devices and the MCP1727-3302E/SN by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the LDL212DR?

5 boards in 5 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
