GENERAL DESCRIPTION
The ADP3303 is a member of the ADP3300, ADP3301, and ADP3309 family of precision low dropout anyCAP1 voltage regulators. The ADP3303 stands out from the conventional LDOs with a different architecture, an enhanced process, and a different package. Its patented design requires only a 0.47 μF output capacitor for stability.
