TPS77901DGK datasheet by Texas Instruments

TPS77901DGK Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS77901DGK?
  The maximum input voltage that can be applied to the TPS77901DGK 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 essential to use a suitable output capacitor with a minimum capacitance of 10uF and an ESR of less than 1 ohm. Additionally, the input capacitor should be at least 1uF with an ESR of less than 1 ohm.
• What is the minimum input voltage required for the TPS77901DGK to operate?
  The minimum input voltage required for the TPS77901DGK to operate is 2.7V, but it's recommended to keep it above 3V for reliable operation.
• Can I use the TPS77901DGK in a high-temperature environment?
  The TPS77901DGK is rated for operation up to 125°C, but it's essential to ensure that the junction temperature (TJ) does not exceed 150°C. You should also consider the power dissipation and thermal management in your design.
• How do I calculate the power dissipation of the TPS77901DGK?
  The power dissipation of the TPS77901DGK can be calculated using the formula: Pd = (VIN - VOUT) x IOUT + VIN x IQ, where Pd is the power dissipation, VIN is the input voltage, VOUT is the output voltage, IOUT is the output current, and IQ is the quiescent current.
