TPS78825DBVR datasheet by Texas Instruments

TPS78825DBVR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS78825DBVR?
  The maximum input voltage that can be applied to the TPS78825DBVR is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a suitable output capacitor with a low equivalent series resistance (ESR) and a high ripple current rating. A 10uF to 22uF ceramic capacitor is recommended.
• What is the minimum input voltage required for the TPS78825DBVR to operate?
  The minimum input voltage required for the TPS78825DBVR to operate is 2.7V, but it's recommended to keep it above 3V for optimal performance.
• Can I use the TPS78825DBVR in a high-temperature environment?
  The TPS78825DBVR is rated for operation up to 125°C, but it's essential to ensure that the device is properly heatsinked and that the junction temperature is kept below 150°C to prevent damage.
• How do I calculate the output voltage of the TPS78825DBVR?
  The output voltage of the TPS78825DBVR can be calculated using the formula: Vout = 1.24V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
