Low Ripple Configuration

Low Ripple Configuration
For applications where lower output voltage ripple is required the output load can be connected directly to
the low ESR output capacitor, as shown below. The evaluation board is laid out in such a way that, user
can use either (high ripple or low ripple) options by simply shifting the output connector. The series
resistor (R) will degrade the load regulation however.
