**Texas Instruments** · Voltage Reference · TO-92-3

TL430CLP 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 | REF | input | Reference input of the shunt regulator, where VI(ref) is 2.5 V min, 2.75 V typ and 3 V max at IZ = 10 mA, and the output voltage is set from it by external resistors R1 and R2. |
| 2 | ANODE | passive | Common terminal to which all voltage values are referenced, and the regulator current IZ must stay within 2 mA min to 100 mA max over the recommended operating range. |
| 3 | CATHODE | passive | Regulated terminal, where the regulator voltage VZ is limited to 30 V maximum with respect to the anode and the continuous regulator current is rated at 150 mA maximum. |
