LT1931AES5 Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LT1931AES5 is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
-
To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10nF to 100nF capacitor between the VIN and GND pins to filter out noise.
-
The LT1931AES5 can deliver a minimum output current of 1mA, but it's recommended to keep the output current above 5mA to ensure optimal performance and accuracy.
-
The LT1931AES5 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliability and prevent thermal shutdown.
-
The output voltage of the LT1931AES5 can be adjusted by changing the ratio of the resistors R1 and R2 in the feedback network. Use the formula VOUT = 1.25V x (1 + R2/R1) to calculate the desired output voltage.
