TLV431IDBVR

Texas Instruments · Voltage Reference · SOT-23-5

TLV431IDBVR 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 SUBSTRATE passive Substrate connection; must be connected to ANODE or left open.
3 CATHODE bidirectional Shunt current/voltage input; cathode voltage operates between VREF and 6 V with cathode current of 0.1 mA to 15 mA recommended.
4 REF input Threshold relative to common anode; reference current must stay between -0.05 mA and 3 mA (absolute maximum).
5 ANODE power_in Common pin, normally connected to ground.

CAD (KiCad official)

  • Symbol: TLV431IDBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tlv431idbvr-etched.step / tlv431idbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlv431idbvr.step / tlv431idbvr.glb are the bare package body.
