The maximum input voltage that can be applied to the TPS73125DBVTG4 is 12V, but it's recommended to keep it below 10V to ensure reliable operation and to prevent damage to the internal voltage regulator.
To ensure the stability of the output voltage, it's recommended to use a minimum output capacitance of 2.2uF and a maximum ESR of 1 ohm. Additionally, the input capacitance should be at least 1uF and the input voltage should be well-regulated.
The maximum output current that the TPS73125DBVTG4 can deliver is 150mA. However, it's recommended to keep the output current below 100mA to ensure reliable operation and to prevent overheating.
The TPS73125DBVTG4 has a built-in thermal shutdown feature that turns off the output when the junction temperature exceeds 150°C. To handle thermal shutdown, ensure good thermal design and heat sinking, and consider adding thermal monitoring and shutdown circuitry in the system design.
The TPS73125DBVTG4 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation. Consult the datasheet and application notes for more information on high-temperature operation.
