DS8604-A0S3 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 pin (接地); the datasheet's absolute maximum ratings reference VIN to GND at -0.3V to 60V and VOUT to GND at -0.3V to 14.0V. |
| 2 | VOUT | power_out | Power output port; the datasheet rates VOUT to GND at -0.3V to 14.0V and recommends an effective output capacitance of 1uF to 22uF with ESR above 1mΩ placed close to VOUT and GND. |
| 3 | VIN | power_in | Power input port; the recommended input voltage range is 2.0V to 55V, and a 1uF or larger input capacitor should be placed close to VIN and GND. |
