TLVH431BQPK

Texas Instruments · Voltage Reference · SOT-89-3

TLVH431BQPK from Texas Instruments, in a SOT-89-3. 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 REF input Reference voltage threshold input; operates within reference current range of -0.05 mA to 3 mA.
2 ANODE power_in Common return pin normally connected to ground for circuit reference.
3 CATHODE bidirectional Regulated shunt cathode node with output voltage range from 1.24V to 18V and continuous operating current from 0.1 to 70 mA.
