DX27641 from Dersem, in a SOT-23-3. 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 | VC | input | VC is the control port of the ripple-filter circuit, with an absolute voltage limit of -0.3 V to 7 V. |
| 2 | GND | power_in | GND is the chip ground pin; the datasheet gives no separate electrical limit for it. |
| 3 | OUT | output | OUT is the output port of the ripple-filter circuit, with an absolute voltage limit of -0.3 V to 60 V. |
