LM2750LD-5.0 from Texas Instruments, in a WSON-10-EP(3x3). 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 | VOUT | power_out | Output voltage pin; it must be connected externally (VOUT pins 1 and 2 are tied together). |
| 2 | VOUT | power_out | Output voltage pin; it must be connected externally (VOUT pins 1 and 2 are tied together). |
| 3 | GND | power_in | On the LM2750-5.0 this pin is GND and must be connected externally to the ground pins (pins 5, 6, and the DAP); on the LM2750-ADJ it is FB. |
| 4 | SD | input | Active-low shutdown input; an internal 200-kΩ resistor to GND pulls it to 0 V and shuts the part down when the pin is left floating. |
| 5 | GND | power_in | Ground pin that must be connected externally (to pins 3, 6 and the DAP). |
| 6 | GND | power_in | Ground pin that must be connected externally (to pins 3, 5 and the DAP). |
| 7 | CAP- | passive | Flying capacitor negative terminal, connected to the external flying capacitor. |
| 8 | VIN | power_in | Input voltage pin; it must be connected externally (VIN pins 8 and 9 are tied together). |
| 9 | VIN | power_in | Input voltage pin; it must be connected externally (VIN pins 8 and 9 are tied together). |
| 10 | CAP+ | passive | Flying capacitor positive terminal, connected to the external flying capacitor. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
