TPS78625DCQR datasheet by Texas Instruments

TPS78625DCQR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS78625DCQR can handle?
  The TPS78625DCQR can handle a maximum input voltage of 15V, but it's recommended to keep the input voltage below 12V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure stability, it's essential to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of 0.1 ohms or less, and to place the capacitor close to the output pin of the regulator.
• What is the dropout voltage of the TPS78625DCQR?
  The dropout voltage of the TPS78625DCQR is approximately 300mV at an output current of 1A, which means the input voltage can be as low as 300mV above the output voltage and still maintain regulation.
• How do I calculate the power dissipation of the TPS78625DCQR?
  To calculate the power dissipation, use the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current. Make sure to consider the thermal resistance and maximum junction temperature to ensure reliable operation.
• Can I use the TPS78625DCQR in a high-temperature environment?
  The TPS78625DCQR is rated for operation up to 125°C, but it's essential to consider the thermal design and heat sinking to ensure reliable operation in high-temperature environments.
