LP3872EMP-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 low to disable regulator with typical quiescent current of 10 nA; pull high through 10-kΩ resistor or leave floating to enable normal operation; maximum voltage rating 7 V. |
| 2 | IN | power_in | Input supply voltage; accepts supply range of 2.5 V to 7 V for regulator operation. |
| 3 | OUT | output | Regulated output voltage with output accuracy of ±1.5% at room temperature and ±3.0% over operating conditions; delivers ensured output current of 1.5 A DC; ultralow dropout of 380 mV at 1.5 A load current. |
| 4 | ERROR | output | Error flag output; pulls low when output voltage drops 10% below nominal value indicating voltage dropout; must be pulled high through 10-kΩ pullup resistor; available only on LP3872. |
| 5 | GND | power_in | Ground connection providing return path for input and output currents; ground pin current typically 6 mA at 1.5 A load current. |
