TPS77901DGKR datasheet by Texas Instruments

TPS77901DGKR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS77901DGKR?
  The maximum input voltage that can be applied to the TPS77901DGKR is 15V, but it's recommended to keep it below 13.2V for 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 TPS77901DGKR to operate?
  The minimum input voltage required for the TPS77901DGKR to operate is 2.7V, but it's recommended to keep it above 3V for reliable operation.
• Can I use the TPS77901DGKR in a high-temperature environment?
  The TPS77901DGKR 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 TPS77901DGKR?
  The output voltage of the TPS77901DGKR can be calculated using the formula: Vout = 1.185V x (1 + R1/R2), where R1 and R2 are the resistors used to set the output voltage.
