16 / 29 page  AS1345 – 16 ams Datasheet, Confidential: 2013-Nov [1-51] De tail ed De sc rip t ion For improved regulation speed and lower ripple C3 should be applied. For best ripple performance always the adjustable variant of the AS1345 together with C3 should be used. Other measures to reduce the ripple could be to select a low peak current IPEAK and increase C4 and to decrease the value of L.
