TPS73025YZQR datasheet by Texas Instruments

TPS73025YZQR Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value for the TPS73025YZQR?
  The recommended input capacitor value is 1uF to 10uF, depending on the input voltage and output current requirements. A larger capacitor can help reduce input voltage ripple and improve overall system stability.
• How do I ensure the TPS73025YZQR is stable and does not oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and keep the input and output capacitors close to the device. Additionally, avoid using long traces and minimize the distance between the input and output pins.
• What is the maximum output current I can draw from the TPS73025YZQR?
  The maximum output current is 250mA, but it's recommended to derate the output current based on the ambient temperature and input voltage. Refer to the datasheet's thermal derating curves for more information.
• Can I use the TPS73025YZQR in a high-temperature environment?
  The TPS73025YZQR is rated for operation up to 125°C, but its performance and reliability may degrade at high temperatures. Make sure to follow the recommended operating conditions and derate the output current accordingly.
• How do I calculate the power dissipation of the TPS73025YZQR?
  The power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current. Refer to the datasheet for more information on how to calculate the quiescent current.
