TPS77025DBVRG4 datasheet by Texas Instruments

TPS77025DBVRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS77025DBVRG4?
  The maximum input voltage that can be applied to the TPS77025DBVRG4 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 in the TPS77025DBVRG4?
  To ensure the stability of the output voltage, it's recommended to use a minimum output capacitance of 2.2uF and a maximum ESR of 1 ohm. Additionally, the input capacitor should be at least 1uF with an ESR of 0.1 ohm or less.
• What is the maximum output current that the TPS77025DBVRG4 can deliver?
  The maximum output current that the TPS77025DBVRG4 can deliver is 50mA. However, it's recommended to keep the output current below 30mA to ensure reliable operation and minimize power dissipation.
• How do I handle the thermal shutdown feature of the TPS77025DBVRG4?
  The TPS77025DBVRG4 has a built-in thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. To handle this feature, ensure that the device is properly heatsinked and that the ambient temperature is kept below 70°C.
• Can I use the TPS77025DBVRG4 in a high-temperature environment?
  The TPS77025DBVRG4 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
