TPS7148QD Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS7148QD is 5.5V, as specified in the absolute maximum ratings section of the datasheet. Exceeding this voltage can cause damage to the device.
  • To ensure stability of the output voltage, it is recommended to use a minimum output capacitance of 1uF and a maximum ESR of 1 ohm, as specified in the datasheet. Additionally, the input voltage should be filtered to reduce noise and ripple.
  • The minimum input voltage required for the TPS7148QD to operate is 2.7V, as specified in the electrical characteristics section of the datasheet. However, the output voltage regulation may not be guaranteed below 2.9V.
  • The TPS7148QD is rated for operation up to 125°C, but the output current and voltage regulation may be affected at high temperatures. It is recommended to derate the output current and voltage according to the thermal derating curves provided in the datasheet.
  • The power dissipation of the TPS7148QD 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. The maximum power dissipation is limited by the thermal resistance and maximum junction temperature.
