LTR3312T20YT3 from Guestgood, 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 | VIN | power_in | Power supply voltage input, 2.7 V to 5.5 V; the datasheet requires VIN of at least VOUT + 0.2 V, and a low-ESR 1 µF ceramic bypass capacitor is recommended at this pin. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | REF | output | Reference voltage output, sourcing and sinking ±5 mA, which requires an external capacitor of 0.1 µF to 10 µF (capacitive load range 0.1 to 10 µF). |
