LP5907QMFX-2.8Q1 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; requires 1-µF input capacitor. |
| 2 | GND | power_in | Common ground. |
| 3 | EN | input | Logic enable input; voltage ≥ 1.2 V enables regulator, ≤ 0.4 V disables regulator with 230-Ω output discharge; internal 1-MΩ pull-down to ground. |
| 4 | N/C | unconnected | No internal electrical connection. |
| 5 | OUT | power_out | Regulated output voltage, 2.8 V nominal; requires 1-µF to 10-µF ceramic capacitor with ESR 5 to 500 mΩ; 230-Ω pull-down discharges when disabled. |
