L79L12ACD13TR

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

L79L12ACD13TR 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 negative output voltage of the L79L12AC regulator, nominal -12 V, delivering up to 100 mA.
2 VIN power_in Unregulated negative DC input voltage to the regulator; this pin is internally commoned to pins 3, 6, 7 and to the die-attach flag for improved thermal dissipation.
3 VIN power_in Unregulated negative DC input voltage to the regulator; this pin is internally commoned to pins 2, 6, 7 and to the die-attach flag for improved thermal dissipation.
4 NC unconnected Not internally connected.
5 GND power_in Ground/common reference pin for the regulator.
6 VIN power_in Unregulated negative DC input voltage to the regulator; this pin is internally commoned to pins 2, 3, 7 and to the die-attach flag for improved thermal dissipation.
7 VIN power_in Unregulated negative DC input voltage to the regulator; this pin is internally commoned to pins 2, 3, 6 and to the die-attach flag for improved thermal dissipation.
8 NC unconnected Not internally connected.

CAD (KiCad official)

  • Symbol: L79L12ACD13TR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: l79l12acd13tr-etched.step / l79l12acd13tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); l79l12acd13tr.step / l79l12acd13tr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
