The maximum input voltage that can be applied to the TPS7225QD 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 with an ESR of 0.1Ω or less, as specified in the datasheet. Additionally, the input capacitor should be at least 1uF with an ESR of 0.1Ω or less.
The minimum input voltage required for the TPS7225QD 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 TPS7225QD 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 input voltage according to the thermal derating curves provided in the datasheet.
The power dissipation of the TPS7225QD 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.
