Additional Details:

The UZ1085L-ADJ typically requires two external resistors to set the output voltage. The dropout voltage is usually around 1.3V at full rated current. It is important to consult the datasheet for specific operating conditions and component selection guidelines, including appropriate input and output capacitor values for stability. The operating temperature range is typically -40°C to +125°C. Maximum input voltage is usually around 30V, but the datasheet should be consulted to ensure this limit is not exceeded. Output current is typically 3A.
