The maximum input voltage that can be applied to the TPS7248QD 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 2.2uF and a maximum ESR of 1 ohm, as specified in the datasheet. Additionally, the input capacitance should be at least 1uF to ensure stability.
The minimum input voltage required for the TPS7248QD to operate is 2.7V, as specified in the electrical characteristics section of the datasheet. However, the device can operate down to 2.5V with reduced performance.
The TPS7248QD is rated for operation up to 125°C, but the device's performance and reliability may be affected at high temperatures. It is recommended to derate the output current and voltage according to the thermal characteristics section of the datasheet.
The power dissipation of the TPS7248QD 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 thermal resistance of the package should also be considered to ensure the device does not exceed its maximum junction temperature.
