LP3874EMP-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 | SD | input | Shutdown control input; pull HIGH for normal operation, pull LOW for shutdown with 10-nA quiescent current. |
| 2 | IN | power_in | Input supply voltage from 2.5 V to 7 V. |
| 3 | OUT | power_out | Regulated 5.0 V output with ±1.5% accuracy at room temperature and ±3% over all conditions, supporting up to 0.8 A DC output current. |
| 4 | SENSE | input | Remote voltage sense input for improved load regulation; connection is optional for remote load sensing. |
| 5 | GND | power_in | Ground connection; ground pin current is typically 6 mA at 0.8 A load current. |
