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 input for the LP38693 (SOT-223 package); pulling the pin high or low turns the regulator output on or off. The pin must be below the VEN(OFF) threshold of 0.4 V (max, full temp range) to disable, and above VEN(ON) (1.8 V at VIN=4V, 3.0 V at VIN=6V, 4.0 V at VIN=10V, full temp range) to fully enable; enable-pin leakage is -1 µA to 1 µA (typ 0.001 µA) at VEN=0V or 10V. |+| 2 | NC | unconnected | No internal connection; this pin is not bonded to the die. |+| 3 | OUT | power_out | Regulated output voltage pin (3.3 V nominal for this -3.3 variant, ±2% accuracy at 25°C, ±4% over the full operating temperature range), rated for load currents from 100 µA to 0.5 A with a typical dropout of 65 mV at 100 mA and 330 mV at 500 mA (VO=3.3V). |+| 4 | IN | power_in | Input supply voltage to the regulator; recommended operating range is 2.7 V to 10 V, with an absolute maximum rating of -0.3 V to 12 V with respect to GND. |+| 5 | GND | power_in | Circuit ground for the regulator; for the SOT-223 package this pin is thermally connected to the die and functions as a heat sink when soldered to a large copper plane. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-223-5 |+| Category | Power Management (PMIC) |+| Pins | 5 |++## CAD (KiCad official)++- Symbol: `LP38693MP-3.3`+- Footprint: `Package_TO_SOT_SMD:SOT-223-5`+- 3D model: SOT-223-5, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.45 mm nominal SOT height).
