TPS79225DBVT datasheet by Texas Instruments

TPS79225DBVT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS79225DBVT can handle?
  The TPS79225DBVT can handle a maximum input voltage of 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure stability, it's essential to use a minimum output capacitance of 10uF with an ESR (Equivalent Series Resistance) of 0.1Ω or less, and to place the capacitor close to the output pin of the regulator.
• What is the dropout voltage of the TPS79225DBVT?
  The dropout voltage of the TPS79225DBVT is approximately 300mV at an output current of 150mA, which means the input voltage can be as low as 2.7V + 0.3V = 3.0V for a 2.7V output.
• How do I calculate the power dissipation of the TPS79225DBVT?
  To calculate the power dissipation, use the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
• Is the TPS79225DBVT short-circuit protected?
  Yes, the TPS79225DBVT has built-in short-circuit protection, which limits the output current to prevent damage in case of a short circuit.
