TPS79118DBVT datasheet by Texas Instruments

TPS79118DBVT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS79118DBVT?
  The maximum input voltage that can be applied to the TPS79118DBVT is 15V, but it's recommended to keep it below 13.2V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure the stability of the output voltage, it's essential to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of less than 1 ohm, and to keep the input capacitance as close to the device as possible.
• What is the minimum input capacitance required for the TPS79118DBVT?
  The minimum input capacitance required for the TPS79118DBVT is 1uF, but it's recommended to use a higher value (e.g., 4.7uF) to ensure stability and reduce input voltage ripple.
• Can I use the TPS79118DBVT in a high-temperature environment?
  The TPS79118DBVT is rated for operation up to 125°C, but it's essential to consider the thermal resistance of the package (θJA) and ensure proper heat sinking to prevent overheating.
• How do I calculate the power dissipation of the TPS79118DBVT?
  The power dissipation of the TPS79118DBVT can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
