TPS3123J12DBVR datasheet by Texas Instruments

TPS3123J12DBVR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS3123J12DBVR?
  The maximum input voltage that can be applied to the TPS3123J12DBVR is 15V, but it's recommended to keep it below 13.2V to ensure reliable operation.
• How do I ensure the TPS3123J12DBVR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and keep the input capacitor (if used) as close to the VIN pin as possible.
• What is the minimum ESR required for the output capacitor?
  The minimum ESR required for the output capacitor is 0.1 ohms, but it's recommended to use a capacitor with an ESR of 0.05 ohms or less for optimal performance.
• Can I use the TPS3123J12DBVR in a high-temperature environment?
  The TPS3123J12DBVR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
• How do I calculate the power dissipation of the TPS3123J12DBVR?
  The power dissipation of the TPS3123J12DBVR can be calculated using the formula: Pd = (VIN - VOUT) x IOUT + (VIN x IQ), where IQ is the quiescent current.
