TPS60311DGSR datasheet by Texas Instruments

TPS60311DGSR Frequently Asked Questions (FAQs)

• What is the recommended input capacitor value and type for the TPS60311DGSR?
  A 1-10uF ceramic capacitor with an X5R or X7R dielectric is recommended for the input capacitor (CIN) to ensure stability and low noise.
• How do I optimize the output capacitor selection for the TPS60311DGSR?
  Choose an output capacitor (COUT) with a low ESR (Equivalent Series Resistance) and a value between 1-22uF. A ceramic capacitor with an X5R or X7R dielectric is recommended. The output capacitor value and type affect the regulator's stability, output noise, and transient response.
• What is the maximum input voltage that the TPS60311DGSR can handle?
  The TPS60311DGSR can handle a maximum input voltage of 5.5V, but it's recommended to keep the input voltage below 5V to ensure reliable operation and minimize power dissipation.
• How do I ensure the TPS60311DGSR operates within its thermal limits?
  Ensure good thermal design and layout practices, such as providing adequate heat sinking, using a thermally conductive PCB material, and keeping the device away from heat sources. Monitor the junction temperature (TJ) and keep it below the maximum rating of 150°C.
• Can I use the TPS60311DGSR in a high-temperature environment?
  Yes, the TPS60311DGSR is rated for operation up to 125°C, but the output voltage accuracy and stability may degrade at higher temperatures. Ensure proper thermal design and derate the output current accordingly.
