SNVS413A – JANUARY 2006 – REVISED APRIL 2013

Output voltage regulation is based on ripple voltage at the feedback input, requiring a minimum amount of ESR

for the output capacitor C2. The LM2695 requires a minimum of 25 mV of ripple voltage at the FB pin. In cases

where the capacitor’s ESR is insufficient additional series resistance may be required (R3 in Typical Application

Circuit and Block Diagram).

For applications where lower output voltage ripple is required the output can be taken directly from a low ESR

output capacitor as shown in Figure 5. However, R3 slightly degrades the load regulation.
