LP38692MPX-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 allows device to be turned ON and OFF via logic level control, with output disabled when VEN ≤ 0.4 V and enabled when VEN ≥ VEN(ON) threshold. |
| 2 | NC | unconnected | No connection; pin is not used in this package variant. |
| 3 | OUT | output | Regulated output voltage of 3.3 V with ±2.5% tolerance at 25°C and 1 A maximum continuous output current. |
| 4 | IN | power_in | Input supply voltage to regulator with operating range 2.7 V to 10 V; minimum must be VOUT + 0.5 V or 2.7 V for proper output regulation. |
| 5 | GND | power_in | Circuit ground reference for regulator; thermally connected to die and functions as heat sink when soldered to copper plane. |
