TPS79225DBVTG4 datasheet by Texas Instruments

TPS79225DBVTG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS79225DBVTG4?
  The maximum input voltage is 5.5V, but it's recommended to keep it below 5V to ensure reliable operation and minimize power dissipation.
• How do I ensure the TPS79225DBVTG4 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (e.g., 10uF), and keep the input voltage ripple below 100mV.
• What is the minimum input voltage required for the TPS79225DBVTG4 to operate?
  The minimum input voltage is 2.2V, but it's recommended to keep it above 2.5V to ensure reliable operation and maintain the specified output voltage accuracy.
• Can I use the TPS79225DBVTG4 in a high-temperature environment?
  The TPS79225DBVTG4 is rated for operation up to 125°C, but it's essential to consider the power dissipation and thermal management to ensure reliable operation in high-temperature environments.
• How do I calculate the output voltage of the TPS79225DBVTG4?
  The output voltage is set by the resistor divider network (R1 and R2) connected to the FB pin. Use the formula: Vout = 0.8V * (1 + R2/R1) to calculate the output voltage.
