TLVH431AIL3T

STMicroelectronics · Voltage Reference · SOT-23-3

TLVH431AIL3T from STMicroelectronics, 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; external resistor divider sets the adjustable output (shunt) voltage from 1.24 V to 18 V; typical reference input current is 1.5 µA (2.5 µA max) with R1=10 kΩ, R2=∞.
2 CATHODE passive Cathode (K) terminal of the shunt regulator; sinks the regulated current from 100 µA min to 60 mA max, with cathode-to-anode voltage from Vref up to 18 V.
3 ANODE power_in Anode (A) terminal, the low-side/ground reference of the shunt regulator against which the cathode-to-anode voltage (VKA, up to 22 V absolute max) is measured.
