LR431AKLT1G from LRC, in a SOT-23. 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 pin connected to internal 2.5 V error-amplifier; reference input current Iref 0.5 µA typ / 1.2 µA max (IKA = 10 mA, R1 = 10 kΩ); full-temperature deviation 0.4 µA typ / 1.2 µA max. |
| 2 | K | power_in | Cathode terminal; regulated supply node with VKA range VREF to 36 V; continuous cathode current −100 mA to +150 mA; minimum cathode current for regulation 0.08 mA typ / 0.3 mA max; dynamic impedance 0.1 Ω typ at 1 kHz. |
| 3 | A | power_in | Anode terminal; connect to circuit ground reference; all voltages and the 2.5 V internal reference are measured with respect to this pin. |
