TPS79025DBVT datasheet by Texas Instruments

TPS79025DBVT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS79025DBVT?
  The maximum input voltage that can be applied to the TPS79025DBVT is 15V, but it's recommended to keep it below 13.2V to ensure reliable operation.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the input capacitance should be at least 1uF.
• What is the minimum input voltage required for the TPS79025DBVT to operate?
  The minimum input voltage required for the TPS79025DBVT to operate is 2.7V, but it's recommended to keep it above 3.5V for reliable startup.
• Can I use the TPS79025DBVT in a high-temperature environment?
  The TPS79025DBVT is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the TPS79025DBVT?
  The output voltage of the TPS79025DBVT can be calculated using the formula: Vout = 1.221 * (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
