Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-5
LP38693MPX-5.0 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 or low turns the regulator ON and OFF. |
| 2 | NC | unconnected | No internal connection. |
| 3 | OUT | power_out | Regulated output voltage, specified for load currents from 100 µA to 0.5 A. |
| 4 | IN | power_in | Input supply voltage to the regulator, with a recommended VIN range of 2.7 V to 10 V. |
| 5 | GND | power_in | Circuit ground, thermally connected to the die so it acts as a heat sink when soldered to a large copper plane. |
