DS8572-30S5 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, recommended 2.3V to 6V with absolute maximum VIN and EN to GND of -0.3V to 7V; place a 1uF or larger input capacitor close to VIN and GND. |
| 2 | GND | power_in | Ground reference for the regulator; output and input capacitor ground connections must return to this pin using short, wide traces. |
| 3 | EN | input | Enable control input with VIH of 1.0V (rising) and VIL of 0.4V (falling); pulling it low puts the part in shutdown with about 100nA typical shutdown current, and absolute maximum is -0.3V to 7V to GND. |
| 4 | NC | unconnected | No internal connection on this pin. |
| 5 | VOUT | power_out | Regulated output of the LDO rated for up to 600mA, with VOUT to GND limited to -0.3V to 6V; use an output capacitor of 1uF to 22uF with minimum 1mΩ ESR placed close to VOUT and GND. |
