DSTECH · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3
DS8575-33S3 from DSTECH, in a SOT-23-3. 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 | GND | power_in | Ground reference pin of the regulator; input and output capacitor ground returns must connect back to this pin using as wide and short a trace as practical. |
| 2 | VOUT | power_out | Regulated output of the LDO; the output capacitor must be placed close to VOUT and GND and meet a minimum 1mΩ ESR with effective capacitance between 1µF and 22µF. |
| 3 | VIN | power_in | Supply input of the regulator, rated 1.2V to 5.5V, which requires a 1µF or larger input capacitor placed close to the VIN and GND pins. |
