TLV431BIDBZR

Texas Instruments · Voltage Reference · SOT-23-3

TLV431BIDBZR from Texas Instruments, in a SOT-23-3. 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 input pin; the device maintains this pin at 1.24 V ±0.5% relative to the anode and requires a minimum reference terminal current of 0.5 µA.
2 CATHODE output Shunt regulation output pin; cathode voltage is regulated from 1.24 V to 6 V with recommended cathode current of 0.1 mA to 15 mA and absolute maximum continuous current of ±20 mA.
3 ANODE power_in Common anode pin, typically connected to ground; serves as the voltage reference node for the device.
