DS8571-30S5 from DSTECH, in a SOT-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 | VIN | power_in | Input of supply voltage, specified for 2.3V to 6V with absolute maximum VIN to GND of -0.3V to 7V, and a 1µF or larger input capacitor should be placed close to VIN and GND. |
| 2 | GND | power_in | Ground reference for the regulator; input and output capacitor ground connections should return to this pin through as wide and short a copper trace as practical. |
| 3 | EN | input | Enable control input, with EN rising threshold VIH of 1.0V and falling threshold VIL of 0.4V, and absolute maximum of -0.3V to 6V to GND; pulling it low puts the part in shutdown with about 0.1µA typical current. |
| 4 | NC | unconnected | No internal connection on this variant (the SNS sense pin exists only on the DS8571N version), so it can be left unconnected. |
| 5 | VOUT | power_out | Output of the regulator, which requires an output capacitor between 1µF and 22µF with minimum 1mΩ ESR placed close to VOUT and GND; the output is current limited to 550mA typical and VOUT to GND is rated -0.3V to 6V. |
