The maximum input voltage that can be applied to the TPS79101DBVRG4 is 5.5V, as specified in the datasheet. However, it's recommended to operate the device within the recommended input voltage range of 2.7V to 5.5V for optimal performance and reliability.
To ensure the stability of the output voltage, it's essential to follow the recommended layout and component selection guidelines provided in the datasheet. This includes using a suitable output capacitor with a low ESR, placing the input and output capacitors close to the device, and minimizing the loop area of the power traces.
The minimum input capacitance required for the TPS79101DBVRG4 is 1uF, as specified in the datasheet. However, it's recommended to use a higher value capacitor, such as 4.7uF or 10uF, to ensure stable operation and to filter out noise and ripple on the input voltage.
The TPS79101DBVRG4 is rated for operation up to 125°C, but it's essential to consider the thermal design and layout of your system to ensure that the device operates within its recommended temperature range. You should also consider the derating of the device's performance and reliability at high temperatures.
The power dissipation of the TPS79101DBVRG4 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. You should also consider the quiescent current and the power dissipation of the device in shutdown mode.
