LP5907MFX-4.5 from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Input voltage supply, 2.2 V to 5.5 V (recommended). Connect a 1-µF ceramic capacitor from this pin to GND close to the device. |
| 2 | GND | power_in | Common ground reference. All voltages are referenced to this pin. |
| 3 | EN | input | Enable input. A low voltage (<VIL) turns the regulator off and discharges VOUT through an internal 230-Ω pulldown. A high voltage (>VIH) enables the regulator. Has an internal 1-MΩ pulldown that holds the regulator off by default; VEN range 0 V to 5.5 V. |
| 4 | NC | unconnected | No internal electrical connection. May be left floating or tied to GND. |
| 5 | OUT | power_out | Regulated 4.5-V output, up to 250 mA. Connect a minimum 1-µF low-ESR ceramic capacitor from this pin to GND. An internal 230-Ω (typical) pulldown discharges VOUT when the regulator is in shutdown (EN low). |
