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.
