TPS79401DCQ Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS79401DCQ is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.
  • To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a high ripple current rating. A 10uF ceramic capacitor is recommended.
  • The minimum input capacitance required for the TPS79401DCQ is 1uF, but it's recommended to use a 4.7uF or 10uF capacitor to ensure stability and to filter out noise.
  • The TPS79401DCQ is rated for operation up to 125°C, but it's essential to consider the thermal design and ensure that the device is properly cooled to prevent overheating and reduce the risk of failure.
  • The output voltage of the TPS79401DCQ can be calculated using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
