Additional Details

The AZ1085S2-5.0 is typically available in a TO-263 package, which provides good thermal dissipation. It requires input and output capacitors for stability and optimal performance. The low dropout voltage characteristic is particularly useful in applications where the input voltage is close to the desired output voltage. Always consult the official datasheet from BCD Semiconductor Manufacturing Limited for detailed specifications, including input voltage range, output voltage tolerance, thermal resistance, and recommended capacitor values. Keep in mind its EOL status when considering this part for new designs.
