LDK130M18R from STMicroelectronics, 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 | IN | power_in | Input voltage supply to the LDO regulator, operating range 1.9 V to 5.5 V |
| 2 | GND | power_in | Common ground reference |
| 3 | EN | input | Enable pin logic control input: low = shutdown mode with quiescent current <1 µA, high = active regulator operation |
| 4 | BYP | passive | Bypass capacitor connection point for output noise reduction on fixed versions (optional, pin must be left floating with no board routing if not used) |
| 5 | OUT | output | Regulated output voltage with 300 mA guaranteed output current and 100 mV typical dropout voltage at 100 mA load |
