DS8201-50F8 from DSTECH, in a ESOP-8. 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 | VOUT | power_out | Regulated output port; for DS8201-50 the absolute maximum VOUT-to-GND rating is -0.3V to 6V, output current is limited to 140mA typical, and the output capacitor (1uF to 22uF effective, ESR above 1mΩ) should sit close to VOUT and GND. |
| 2 | SNS | input | Output voltage sense input used to set the output voltage through the feedback divider from VOUT; for DS8201-50 the absolute maximum SNS-to-GND rating is -0.3V to 6V, and divider current should exceed 50uA. |
| 3 | NC | unconnected | No internal connection; the datasheet specifies this pin as floating. |
| 4 | GND | power_in | Ground reference pin; input and output capacitor ground connections must return directly to this pin using short, wide traces. |
| 5 | EN | input | Enable control: pulling EN low enters shutdown mode (about 0.1uA typical shutdown current), with the EN rising threshold VIH of 3.0V and falling threshold VIL of 0.6V. |
| 6 | NC | unconnected | No internal connection; the datasheet specifies this pin as floating. |
| 7 | NC | unconnected | No internal connection; the datasheet specifies this pin as floating. |
| 8 | VIN | power_in | Power input; recommended input voltage is 3.0V to 110V, absolute maximum VIN-to-GND rating is -0.3V to 125V, and a 1uF or larger input capacitor should be placed close to VIN and GND. |
| 9 | Exposed Pad | passive | Exposed thermal pad for heat dissipation, which may be left floating or connected to GND. |
