APX803-46SAG-7 datasheet by Diodes Incorporated

APX803-46SAG-7 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the APX803-46SAG-7 can handle?
  The APX803-46SAG-7 can handle a maximum input voltage of 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and keep the ESR (Equivalent Series Resistance) below 1 ohm. Also, avoid using ceramic capacitors with high ESR values.
• What is the maximum output current that the APX803-46SAG-7 can provide?
  The APX803-46SAG-7 can provide a maximum output current of 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
• How do I calculate the power dissipation of the APX803-46SAG-7?
  To calculate the power dissipation, use the formula: Pd = (Vin - Vout) x Iout. Make sure to consider the thermal resistance (RθJA) and the maximum junction temperature (Tj) to ensure the device operates within safe limits.
• What is the purpose of the EN (Enable) pin?
  The EN pin is used to enable or disable the voltage regulator. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled. This pin can be used to implement power-saving features or to control the regulator's operation.
