MP3217DJ-LF-Z from Monolithic Power Systems, in a TSOT-23-6. 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 | PGND | power_in | Power ground pin for the internal power switch return path, to be kept separate from the signal ground GND pin. |
| 2 | GND | power_in | Ground pin, where the input and output capacitor ground returns should be tied close to the device. |
| 3 | FB | input | Feedback input with a 1.24V reference voltage, connected to a resistor divider from the output. |
| 4 | EN | input | ON/OFF control input where a voltage above 2V turns the part on and below 0.8V turns it off, and floating EN to the input source gives automatic startup when unused. |
| 5 | IN | power_in | Input supply pin that must be locally bypassed, with an operating input voltage of 2.5V to 6V. |
| 6 | SW | output | Power switch output that is the drain of the internal MOSFET, to which the power inductor and output rectifier connect, with SW rated from VIN to 36V. |
