TPS78633DCQR Frequently Asked Questions (FAQs)

The TPS78633DCQR can handle input voltages up to 17V, but it's recommended to keep the input voltage below 15V for optimal performance and reliability.
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.
The dropout voltage of the TPS78633DCQR is typically around 300mV at an output current of 1A, but it can vary depending on the input voltage and output current.
The TPS78633DCQR 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.
The power dissipation of the TPS78633DCQR 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.
