TPS3705-33DR datasheet by Texas Instruments

TPS3705-33DR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS3705-33DR?
  The maximum input voltage that can be applied to the TPS3705-33DR is 40V, but it's recommended to operate within the specified operating range of 3.3V to 40V to ensure reliable operation.
• How do I ensure the TPS3705-33DR is stable and doesn't oscillate?
  To ensure stability, it's essential to follow the recommended PCB layout guidelines, use a suitable output capacitor, and add a 10nF to 100nF capacitor between the FB and VOUT pins to filter out noise.
• What is the minimum ESR required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.1 ohms. However, it's recommended to use a capacitor with an ESR of 0.01 ohms or less to ensure stability and optimal performance.
• Can I use the TPS3705-33DR in a high-temperature environment?
  The TPS3705-33DR is rated for operation up to 125°C, but it's essential to consider the derating curves and thermal management to ensure reliable operation in high-temperature environments.
• How do I calculate the output voltage tolerance of the TPS3705-33DR?
  The output voltage tolerance of the TPS3705-33DR is ±2% over the entire operating range. To calculate the output voltage tolerance, multiply the output voltage by the tolerance percentage (e.g., 3.3V x 0.02 = ±0.066V).
