LN1131P332MR-G from NATLINEAR, in a SOT-23-3L. 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 | VSS | power_in | Ground pin; it is the reference for the input voltage rating (VSS-0.3 V to VSS+10 V absolute maximum) and the output voltage rating (VSS-0.3 V to VIN+0.3 V). |
| 2 | VOUT | power_out | Regulated output pin; absolute maximum is VSS-0.3 V to VIN+0.3 V, and output current reaches 300 mA when VIN is at least VOUT+1 V. |
| 3 | VIN | power_in | Input pin; the datasheet gives an input voltage range of 1.8 V to 7 V, with a maximum of 7 V in the features list. |
