TPS73125DBVRG4 datasheet by Texas Instruments

TPS73125DBVRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS73125DBVRG4?
  The maximum input voltage that can be applied to the TPS73125DBVRG4 is 12V, but it's recommended to keep it below 10V to ensure reliable operation and to prevent damage to the internal voltage regulator.
• How do I ensure the stability of the output voltage in the TPS73125DBVRG4?
  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 capacitance should be at least 1uF to prevent oscillations.
• What is the power dissipation of the TPS73125DBVRG4?
  The power dissipation of the TPS73125DBVRG4 depends on the input voltage, output voltage, and output current. However, as a general guideline, the maximum power dissipation is around 1.5W. It's recommended to use a heat sink or a thermal pad to ensure reliable operation.
• Can I use the TPS73125DBVRG4 in a high-temperature environment?
  The TPS73125DBVRG4 is rated for operation up to 125°C, but it's recommended to derate the output current and power dissipation at higher temperatures to ensure reliable operation. Additionally, the device should be mounted on a heat sink or a thermal pad to prevent overheating.
• How do I protect the TPS73125DBVRG4 from input voltage transients?
  To protect the TPS73125DBVRG4 from input voltage transients, it's recommended to use a TVS diode or a transient voltage suppressor at the input. Additionally, a capacitor can be used to filter out high-frequency noise and transients.
