TLV431ILPR

Texas Instruments · Voltage Reference · TO-92-3

TLV431ILPR from Texas Instruments, in a TO-92-3. 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 CATHODE output Shunt regulated output; voltage adjustable from 1.24 V to 6 V with external resistor network; absolute maximum continuous cathode current ±20 mA.
2 ANODE power_in Ground return; common pin normally connected to negative supply rail or circuit ground.
3 REF input Reference input pin; voltage applied from external resistor divider between cathode and anode; requires minimum input current 0.5 µA per datasheet Section 5.5.
