TLVH431AIDBZR

Texas Instruments · Voltage Reference · SOT-23

TLVH431AIDBZR from Texas Instruments, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REF input Reference/feedback input. Internal amplifier compares this pin against the internal 1.24 V bandgap reference; when VREF is exceeded the device sinks current from CATHODE to ANODE. Typically driven from a resistor divider between CATHODE and ANODE to set the regulated output voltage.
2 CATHODE bidirectional Shunt current/voltage terminal. Programmable shunt regulator output; sinks current (100 μA to 70 mA operating range) to hold voltage between CATHODE and ANODE at the target set by the REF divider. Typical output impedance 0.25 Ω. Marked 'I/O' in the datasheet Pin Functions table.
3 ANODE power_in Common return terminal, normally tied to ground/low-side of the regulated node. All internal circuit currents flow out this pin. Marked as 'O' (common pin) in the datasheet Pin Functions table.

  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tlvh431aidbzr-etched.step / tlvh431aidbzr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlvh431aidbzr.step / tlvh431aidbzr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (None pp, sha256 773beb10ee51e5d0, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
