TLV431ACDBZR-TP

TECH PUBLIC · Voltage Reference · SOT-23

TLV431ACDBZR-TP from TECH PUBLIC, 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 error amplifier compares this pin to the internal 1.24 V bandgap; typical input current 0.7 uA, max 4.0 uA. Sets the shunt regulation point via an external R1/R2 divider (Vka = Vref*(1 + R1/R2) + Iref*R1).
2 CATHODE power_in Cathode (K) of the shunt regulator. Sinks the regulated shunt current; continuous cathode current range 0.1 mA to 100 mA (absolute max -100 to +150 mA). Vka rated up to 18 V; dynamic impedance ~0.05 Ω typical.
3 ANODE power_in Anode (A) of the shunt regulator; the ground/return reference for all voltages on the device.
