Texas Instruments · DC-DC Converters · SOT-23-5
LM2735XQMFX from Texas Instruments, in a SOT-23-5. 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 | SW | output | Output switch. Connect to the inductor, output diode. |
| 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. Connect FB to external resistor-divider to set output voltage. |
| 4 | EN | input | Shutdown control input. Logic high enables operation. Do not allow this pin to float or be greater than VIN + 0.3 V. |
| 5 | VIN | power_in | Supply voltage for power stage, and input supply voltage. |
