TPS78918DBVR datasheet by Texas Instruments

TPS78918DBVR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS78918DBVR?
  The maximum input voltage that can be applied to the TPS78918DBVR is 13.2V, but it's recommended to keep it below 12V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of 1 ohm or less, and to place the capacitor close to the output pin of the regulator.
• What is the minimum input capacitance required for the TPS78918DBVR?
  The minimum input capacitance required for the TPS78918DBVR is 1uF, but it's recommended to use a higher value (e.g., 4.7uF) to ensure stability and reduce input voltage ripple.
• Can I use the TPS78918DBVR in a high-temperature environment?
  The TPS78918DBVR is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. It's essential to consider the thermal design and heat dissipation in your application.
• How do I calculate the power dissipation of the TPS78918DBVR?
  The power dissipation of the TPS78918DBVR can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
