78SR112SC Frequently Asked Questions (FAQ)
-
The recommended input capacitor value is 10uF to 22uF, with a voltage rating of at least 25V. This ensures stable operation and reduces noise.
-
The output capacitor value depends on the output voltage, output current, and desired ripple voltage. A general rule of thumb is to use a capacitor with a value of 10uF to 47uF, with a voltage rating of at least 2x the output voltage.
-
The 78SR112SC can handle input voltages up to 35V, but it's recommended to keep the input voltage below 30V to ensure reliable operation and prevent overheating.
-
The 78SR112SC is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to prevent overheating and ensure reliable operation.
-
To reduce noise and ripple voltage, use a high-quality input capacitor, add a noise-reducing capacitor (e.g., 10nF) between the input and ground, and consider using a post-regulator or a noise-reducing filter.
