# TLVH431AIDCKR

**Texas Instruments** · Voltage Reference · SC-70-6

TLVH431AIDCKR from Texas Instruments, in a SC-70-6. 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 regulated output accepting cathode current from -25 mA to +80 mA with regulated voltage between VREF (1.24V) and 18V. |
| 2 | * | unconnected | Substrate contact that must be connected to ANODE or left open. |
| 3 | REF | input | Reference threshold input that adjusts output voltage via external resistor network and accepts reference current from -0.05 mA to +3 mA. |
| 4 | NC | unconnected | No internal connection. |
| 5 | NC | unconnected | No internal connection. |
| 6 | ANODE | power_in | Ground return and voltage reference baseline; common pin normally connected to ground. |
