**DSTECH** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

DS8606-A1A3 from DSTECH, in a SOT-89-3. 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 | VOUT | power_out | Regulator output port, which supplies up to 200 mA of load current and has an absolute maximum rating of -0.3 V to 14 V to GND. |
| 2 | GND | power_in | Ground pin, to which the input and output capacitor ground connections must be returned using short, wide traces. |
| 3 | VIN | power_in | Power input port, with a recommended input voltage range of 2.0 V to 55 V. |
