# TLVH432ACDBZR

**Texas Instruments** · Voltage Reference · SOT-23-3

TLVH432ACDBZR from Texas Instruments, in a SOT-23-3. 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 | bidirectional | Shunt current/voltage input; regulated output terminal operating from VREF (1.24V) to 18V with continuous current range of 0.1mA to 70mA. |
| 2 | REF | input | Reference threshold pin relative to common anode; reference input for voltage regulation with current range -0.05mA to +3mA. |
| 3 | ANODE | power_in | Common pin, normally connected to ground; serves as reference point for voltage and current measurements. |
