LMR10515YMFX from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SW | output | Switch node connected to the inductor and catch diode, driven by internal PWM control logic. |
| 2 | GND | power_in | Signal and power ground pin; place the bottom resistor of the feedback network as close as possible to this pin. |
| 3 | FB | input | Feedback pin connected to external resistor divider to set output voltage with 0.6 V nominal reference. |
| 4 | EN | input | Enable control input with 1.8 V logic-high threshold for operation; must not float or exceed VIN + 0.3 V. |
| 5 | VIN | power_in | Input supply voltage with recommended operating range 3 V to 5.5 V. |
