If the custom er’s application req uires a very low output voltage ripple and / or very low
output voltage overshoot / undershoot during transients, then the guidelines previously
show n need to be exceeded and good layout practices becom e m andatory.
B y using four 330—F O SC O N capacitors, each having E S R = 17m
ripple can be decreased to 50m V pk-pk on a 1.2V output S IP . A lso during a transient load
condition (load current steps from 20% to 100% and back, at 2 A / —sec) the output voltage
does not overshoot / undershoot m ore than 100m V .
W hen fast and deep transient loads are expected, the input capacitor becom es im portant as
w ell, especially if the SIP is far from its input voltage source. C apacitors having as m uch as
2000—F and com bined ES R lower than 20m
P ractical results heavily depend on physical layout and specific load conditions. For critical
applications the custom er is encouraged to consult with the m anufacturer.
