The maximum input voltage that can be applied to the TPS79318DBVRG4 is 5.5V, as specified in the absolute maximum ratings section of the datasheet. Exceeding this voltage can damage the device.
To ensure the output voltage is stable and accurate, make sure to follow the recommended layout and component selection guidelines in the datasheet, including the use of a 1μF ceramic capacitor at the output and a 10nF ceramic capacitor at the input. Additionally, ensure that the input voltage is within the recommended operating range and that the device is operated within the specified temperature range.
The minimum input capacitance required for stable operation is 1μF, as specified in the datasheet. However, it is recommended to use a higher value capacitor, such as 4.7μF or 10μF, to ensure stable operation over a wide range of input voltages and temperatures.
The TPS79318DBVRG4 is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It is recommended to derate the output current and ensure proper thermal management to prevent overheating and ensure reliable operation.
The output voltage of the TPS79318DBVRG4 is determined by the resistor divider network connected to the FB pin. The output voltage can be calculated using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
