The maximum input voltage is 40V, but it's recommended to keep it below 30V for reliable operation.
The output voltage 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 is 7.5V, but it's recommended to keep it above 8V for reliable operation.
The LM2678S-ADJ/NOPB is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Thermal management is crucial in high-temperature environments.
To ensure stability, use a minimum output capacitance of 22µF, and keep the ESR (Equivalent Series Resistance) below 1Ω. Additionally, use a low-ESR input capacitor (e.g., ceramic or film capacitor) to filter the input voltage.
