MP174GJ-Z from Monolithic Power Systems, in a TSOT-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 | VCC | power_in | Control circuit power supply; the datasheet gives an operating VCC range of 5.3V to 5.6V, and the IC stops switching when VCC drops below 3.4V. |
| 2 | FB | input | Regulator feedback input; the datasheet sets the feedback reference at 2.55V, with OLP triggered below 1.7V and open-loop detection below 0.5V. |
| 3 | SOURCE | power_in | Internal power MOSFET source and ground reference for the VCC and FB pins. |
| 4 | SOURCE | power_in | Internal power MOSFET source and ground reference for the VCC and FB pins. |
| 5 | DRAIN | input | Internal power MOSFET drain and high-voltage current source input; the drain-to-source rating is -0.3V to 700V. |
