DS8607-50A3
DSTECH · Linear Voltage Regulators (LDO) · SOT-89-3
DS8607-50A3 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 | GND | power_in | Ground pin; the input and output capacitor ground connections must return to this pin with short, wide traces. |
| 2 | VIN | power_in | Power input port; the datasheet specifies an input voltage range of 2V to 55V and recommends at least 1uF input capacitance placed close to VIN and GND. |
| 3 | VOUT | power_out | Power output port for the fixed output voltage; dropout is 0.66V at VOUT of 5V and ILOAD of 100mA, and the current limit is 300mA typical. |
