TPS72501DCQR datasheet by Texas Instruments

TPS72501DCQR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS72501DCQR?
  The maximum input voltage that can be applied to the TPS72501DCQR is 6.5V. Exceeding this voltage may damage the device.
• How do I ensure stability of the output voltage?
  To ensure stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
• What is the minimum input capacitance required for the TPS72501DCQR?
  The minimum input capacitance required for the TPS72501DCQR is 1uF. However, it is recommended to use a higher capacitance value, such as 4.7uF or 10uF, to ensure stability and reduce input voltage ripple.
• Can I use the TPS72501DCQR in a high-temperature environment?
  The TPS72501DCQR is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
• How do I calculate the power dissipation of the TPS72501DCQR?
  The power dissipation of the TPS72501DCQR 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.
