TLVH431BCPK

Texas Instruments · Voltage Reference · SOT-89-3

TLVH431BCPK 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 Threshold input relative to common anode; receives feedback voltage for comparison with internal 1.24 V reference.
2 ANODE power_in Common pin normally connected to ground; provides return path for the internal current sink.
3 CATHODE bidirectional Shunt-regulated output terminal; regulated voltage from 1.24 V to 18 V appears here while sinking continuous cathode current from 0.1 mA to 70 mA.
