APX803D-29SRG-7 datasheet by Diodes Incorporated

APX803D-29SRG-7 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the APX803D-29SRG-7 can handle?
  The maximum input voltage for the APX803D-29SRG-7 is 30V, but it's recommended to keep it below 28V for reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) should be less than 1 ohm.
• What is the dropout voltage of the APX803D-29SRG-7?
  The dropout voltage is typically around 1.5V, which means the input voltage should be at least 1.5V higher than the output voltage for proper regulation.
• Can I use the APX803D-29SRG-7 in a high-temperature environment?
  The APX803D-29SRG-7 has a junction temperature range of -40°C to 125°C, but the maximum operating temperature is 85°C for reliable operation. Derating is required for higher temperatures.
• How do I calculate the power dissipation of the APX803D-29SRG-7?
  Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
