LM2679S-ADJ Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM2679S-ADJ is 40V. Exceeding this voltage can cause damage to the device.
-
The output voltage of the LM2679S-ADJ can be adjusted by connecting a resistor divider network between the output and the ADJ pin. The voltage is set by the ratio of the resistors and the internal reference voltage (1.21V).
-
The minimum input voltage required for the LM2679S-ADJ to operate is 7.5V. However, the device can operate with an input voltage as low as 7V, but with reduced performance.
-
The LM2679S-ADJ is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the device's output current and voltage at high temperatures.
-
To ensure the stability of the LM2679S-ADJ output voltage, it's recommended to use a minimum output capacitance of 22µF and a maximum ESR of 1Ω. Additionally, the input capacitor should be at least 10µF with an ESR of 0.1Ω or less.
