LP38693MPX-3.3 from Texas Instruments, in a SOT-223-5. 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 | EN | input | Enable pin: pulling it high turns the regulator ON and pulling it low turns it OFF. |
| 2 | N/C | unconnected | No internal connection, per the datasheet NC legend for the NDC package drawing; not assigned in the pin functions table. |
| 3 | OUT | power_out | Regulated output voltage; the electrical characteristics cover load currents from 100 µA to 0.5 A. |
| 4 | IN | power_in | Input supply voltage to the regulator; recommended range is 2.7 V to 10 V, and absolute maximum is 12 V with respect to GND. |
| 5 | GND | power_in | Circuit ground, thermally connected to the die and acting as a heat sink when the tab is soldered to a large copper plane. |
