LDL212DR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOIC-8

LDL212DR from STMicroelectronics, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VOUT power_out Regulated output voltage, adjustable from 1.18 V to VIN-VDROP(MAX) via external resistor divider.
2 GND power_in Ground.
3 GND power_in Ground.
4 VIN power_in Input voltage, 2.5 V to 18 V.
5 EN input Enable pin; device is in off-state when this pin is pulled low.
6 GND power_in Ground.
7 GND power_in Ground.
8 ADJ/sense input Feedback pin for adjustable version; external resistor divider sets output voltage from 1.18 V to VIN-VDROP(MAX).

CAD (KiCad official)

  • Symbol: LDL212DR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: ldl212dr-etched.step / ldl212dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ldl212dr.step / ldl212dr.glb are the bare package body.
