DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5
DS8575-33S5 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 supply voltage with a recommended operating range of 1.2V to 5.5V, and a 1µF or larger input capacitor should be placed close to the VIN and GND pins. |
| 2 | GND | power_in | Ground reference for the regulator, and the input and output capacitor ground connections should return to this pin through as wide and short a copper trace as is practical. |
| 3 | EN | input | Enable control input with VIH of 1.0V (rising) and VIL of 0.4V (falling); pulling it low selects shutdown with a typical shutdown current of 10nA. |
| 4 | NC | unconnected | No internal connection. |
| 5 | VOUT | power_out | Regulated output, which requires an output capacitor between 1µF and 22µF with a minimum 1mΩ ESR placed close to the VOUT and GND pins, with output current limited to 550mA typical. |
