TPS70939DBVT Frequently Asked Questions (FAQs)

  • The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input voltage ripple and improve output voltage regulation.
  • To ensure stability, it is recommended to use a minimum output capacitor of 1uF with an ESR (Equivalent Series Resistance) of less than 1 ohm. Additionally, the input capacitor should be placed close to the regulator and the output capacitor should be placed close to the load.
  • The TPS70939DBVT can handle a maximum input voltage of 12V. Exceeding this voltage may cause damage to the regulator or affect its performance.
  • The TPS70939DBVT is rated for operation up to 125°C. However, the regulator's performance and reliability may be affected at high temperatures. It is recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
  • The output voltage of the TPS70939DBVT is adjustable and can be calculated using the formula: Vout = (R1 / R2) * 1.25V, where R1 and R2 are the resistors connected to the FB pin.
