TLVH431AQDBVRQ1

Texas Instruments · Voltage References · SOT-23-5

TLVH431AQDBVRQ1 from Texas Instruments, in a SOT-23-5. 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 NC unconnected No internal connection.
2 * passive Pin 2 is attached to the substrate and must be connected to ANODE or left open.
3 CATHODE passive Cathode of the shunt regulator, operating from VREF up to 18 V (20 V absolute maximum) with 0.1 mA to 70 mA continuous cathode current.
4 REF input Reference input that sets the output voltage with an external resistor divider against the 1.24 V internal reference.
5 ANODE power_in Anode of the shunt regulator, normally connected to ground, with cathode voltage specified with respect to it.

CAD (KiCad official)

  • Symbol: TLVH431AQDBVRQ1
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tlvh431aqdbvrq1-etched.step / tlvh431aqdbvrq1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlvh431aqdbvrq1.step / tlvh431aqdbvrq1.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (27 pp, sha256 29341c7b849a14b7, retrieved 2026-10-30, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
