TPS3305-18DG4 datasheet by Texas Instruments

TPS3305-18DG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS3305-18DG4?
  The maximum input voltage that can be applied to the TPS3305-18DG4 is 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I ensure the TPS3305-18DG4 is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component selection guidelines, including the use of a 10uF ceramic capacitor at the output and a 1uF ceramic capacitor at the input.
• What is the minimum load current required for the TPS3305-18DG4 to maintain regulation?
  The TPS3305-18DG4 can maintain regulation down to a minimum load current of 1mA, but it's recommended to have a minimum load of 10mA for optimal performance.
• Can I use the TPS3305-18DG4 in a high-temperature environment?
  The TPS3305-18DG4 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage as temperature increases to ensure reliable operation.
• How do I protect the TPS3305-18DG4 from input voltage transients and surges?
  Use a TVS diode or a transient voltage suppressor at the input to protect the TPS3305-18DG4 from voltage transients and surges.
