TLV431BCDCKR-TP

TECH PUBLIC · Voltage Reference · SOT-363

TLV431BCDCKR-TP from TECH PUBLIC, in a SOT-363. 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 CATHODE passive Cathode (K) terminal of the shunt regulator. Sinks the regulated cathode current I_KA (0.1-100 mA continuous, 18 V max). Voltage V_KA is regulated so that V_REF (~1.24 V) appears at the REF pin relative to ANODE.
2 NC unconnected No internal connection. Attached to substrate; must be connected to ANODE or left open.
3 REF input Reference input to the internal error amplifier's non-inverting node. Regulation drives V_REF (typ 1.24 V, 1.234-1.246 V) between REF and ANODE. Reference input current I_REF ~0.7 µA typ (4 µA max).
4 NC unconnected No internal connection. Attached to substrate; must be connected to ANODE or left open.
5 NC unconnected No internal connection. Attached to substrate; must be connected to ANODE or left open.
6 ANODE passive Anode (A) terminal, the ground/return reference for the shunt regulator. All voltages (V_KA, V_REF) are referenced to this pin.
