LP5907MFX-2.85 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 | input | Input voltage supply. Connect a 1µF capacitor at this input. |
| 2 | GND | power_in | Common ground. |
| 3 | EN | input | Enable input. A low voltage (< VIL) on this pin turns the regulator off and discharges the output pin to GND through an internal 230Ω pulldown resistor. A high voltage (> VIH) on this pin enables the regulator output. This pin has an internal 1MΩ pulldown resistor to hold the regulator off by default. |
| 4 | N/C | unconnected | No internal electrical connection. |
| 5 | OUT | output | Regulated output voltage. Connect a minimum 1µF low-ESR capacitor to this pin. Connect this output to the load circuit. An internal 230Ω (typical) pulldown resistor prevents a charge remaining on VOUT when the regulator is in shutdown mode (VEN low). |
