LN1152B282MR-G from NATLINEAR, in a SOT-23-5L. 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 | Input supply pin; operating input voltage range is 2.0 V to 7 V (absolute maximum VSS+8 V). |
| 2 | VSS | power_in | Ground pin of the regulator. |
| 3 | CE | input | Chip enable pin, active high with built-in pull-down resistor (B version); high level minimum 1.6 V, low level maximum 0.5 V. |
| 4 | NC | unconnected | No connection (not connected internally). |
| 5 | VOUT | power_out | Regulated output pin; 2.8 V output with ±2% accuracy for this MPN, up to 500 mA output current when VIN≥VOUT+1 V. |
