TPS79133DBVT datasheet by Texas Instruments

TPS79133DBVT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS79133DBVT?
  The maximum input voltage that can be applied to the TPS79133DBVT 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 of 1 ohm or less, and to place the capacitor close to the output pin of the regulator.
• What is the minimum input capacitance required for the TPS79133DBVT?
  The minimum input capacitance required for the TPS79133DBVT 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 TPS79133DBVT in a high-temperature environment?
  The TPS79133DBVT is rated for operation up to 125°C, but it's essential to consider the thermal resistance of the package and the PCB layout to ensure reliable operation at high temperatures.
• How do I calculate the power dissipation of the TPS79133DBVT?
  The power dissipation of the TPS79133DBVT 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.
