LP5907MFX-1.2 from Texas Instruments, in a SOT-23-5. 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 (2.2V to 5.5V); requires minimum 1µF capacitor connected at this pin. |
| 2 | GND | power_in | Common ground connection. |
| 3 | EN | input | Enable input with internal 1MΩ pulldown resistor; voltage below VIL (0.4V) disables regulator, voltage above VIH (1.2V) enables the regulator output. |
| 4 | N/C | unconnected | No internal electrical connection. |
| 5 | OUT | power_out | Regulated output voltage with internal 230Ω pulldown resistor; requires minimum 1µF low-ESR capacitor connected to this pin. |
