DS8561-28S5 from DSTECH, in a SOT23-5. 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 pin, operating input voltage range 1.2V to 5.5V, with absolute maximum VIN to GND of -0.3V to 7V. |
| 2 | GND | power_in | Ground pin for the regulator; input and output capacitor ground connections must return to this pin with short, wide traces. |
| 3 | EN | input | Enable control input: EN rising threshold VIH is 1.0V and falling threshold VIL is 0.4V, and pulling EN low puts the device into shutdown; absolute maximum EN to GND is -0.3V to 6V. |
| 4 | NC | unconnected | No-connect pin that is left floating and is not connected internally. |
| 5 | VOUT | power_out | Regulated output voltage pin (2.8V for this variant), with absolute maximum VOUT to GND of -0.3V to 6V; output capacitor of 1uF to 22uF with ESR above 1mΩ should be placed close to VOUT and GND. |
