LP38693MP-1.8 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 high turns the regulator output ON and pulling low turns it OFF, with no internal pull-up/pull-down so it must be actively or passively terminated (tie to VIN if unused). |
| 2 | NC | unconnected | No internal connection; this pin is not bonded to the die and can be left unconnected. |
| 3 | OUT | output | Regulated output voltage pin; requires an external ceramic output capacitor (1 µF, ESR 5 mΩ-500 mΩ) to GND for stability. |
| 4 | IN | power_in | Input supply voltage to the regulator, rated 2.7 V to 10 V; a minimum 1 µF capacitor to GND located within 1 cm of this pin is required for stability. |
| 5 | GND | power_in | Circuit ground for the regulator; for the SOT-223 package this pin is thermally connected to the die and acts as a heat sink when soldered to a large copper plane. |
