DS8561-18C5 from DSTECH, in a SC70-5. 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 | VIN | power_in | Power input port; the datasheet gives an input voltage range of 1.2 V to 5.5 V, and a 1 µF or larger input capacitor should be placed close to the VIN and GND pins. |
| 2 | GND | power_in | Ground pin; the input and output capacitor ground connections must return to this pin using short, wide traces. |
| 3 | EN | input | Enable control input; the EN rising threshold VIH is 1.0 V and the falling threshold VIL is 0.4 V, and pulling EN low puts the device in shutdown, with EN absolute maximum of -0.3 V to 6 V to GND. |
| 4 | NC | unconnected | No connection; this pin is floating and is not used internally. |
| 5 | VOUT | power_out | Regulated voltage output; absolute maximum ratings are -0.3 V to 6 V to GND and -6 V to 0.3 V relative to VIN, and an output capacitor of 1 µF to 22 µF with ESR above 1 mΩ is recommended close to VOUT and GND. |
