TLVH431BIPK

Texas Instruments · Voltage Reference · SOT-89-3

TLVH431BIPK from Texas Instruments, in a SOT-89-3. 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 REF input Reference feedback input pin; sets output voltage (1.24V to 18V range) relative to 1.24V internal reference through external resistive divider.
2 ANODE power_in Common pin; provides voltage reference for internal comparator and return path for regulated shunt current.
3 CATHODE output Regulated output pin; maintains programmable voltage (1.24V to 18V) above anode by controlling shunt current within 100µA (minimum for regulation) to 70mA (maximum continuous) range.
