TPS5103IDB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS5103IDB is 18V, but it's recommended to keep it below 15V for reliable operation.
  • To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and add a 1uF capacitor between the VIN and EN pins.
  • The minimum input voltage required for the TPS5103IDB to operate is 2.7V, but it's recommended to keep it above 3.5V for reliable startup and operation.
  • The TPS5103IDB is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. Make sure to follow the recommended operating conditions and derate the output current accordingly.
  • The output voltage of the TPS5103IDB can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
