LP5907QMFX-1.8Q1 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 operating range); connect 1-µF capacitor. |
| 2 | GND | power_in | Common ground. |
| 3 | EN | input | Enable input; logic low (< VIL) disables regulator and discharges output through 230-Ω pulldown resistor; logic high (> VIH) enables regulator output; 1-MΩ pulldown resistor holds regulator off by default. |
| 4 | N/C | unconnected | No internal electrical connection. |
| 5 | OUT | power_out | Regulated output voltage; connect minimum 1-µF low-ESR capacitor; 230-Ω pulldown resistor prevents charge remaining on VOUT when regulator is in shutdown mode (VEN low). |
