TPS2814DRG4 datasheet by Texas Instruments

TPS2814DRG4 Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS2814DRG4?
  The maximum input voltage that can be applied to the TPS2814DRG4 is 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I calculate the output voltage of the TPS2814DRG4?
  The output voltage of the TPS2814DRG4 can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vref), where R1 and R2 are the resistors connected to the FB pin, Vin is the input voltage, and Vref is the internal reference voltage (1.22V).
• What is the minimum input voltage required for the TPS2814DRG4 to operate?
  The minimum input voltage required for the TPS2814DRG4 to operate is 2.5V, but it's recommended to keep it above 3V for reliable operation.
• Can I use the TPS2814DRG4 as a high-current regulator?
  The TPS2814DRG4 is designed for low-to-moderate current applications (up to 1.5A). For high-current applications, it's recommended to use a different regulator or add external components to ensure reliable operation.
• How do I ensure stability and prevent oscillations in the TPS2814DRG4?
  To ensure stability and prevent oscillations, it's recommended to use a minimum output capacitance of 10uF, keep the input and output capacitors close to the regulator, and use a low-ESR capacitor for the output.
