MC33762 Voltage Regulator - Dual, Ultra Low-Noise, Low Dropout, ON/OFF Control 1.0 V The MC33762 is a dual Low DropOut (LDO) regulator featuring excellent noise performances. Thanks to its innovative design, the circuit reaches an impressive 40 mVRMS noise level without an external bypass capacitor. Housed in a small m8 package, it represents the ideal designer’s choice when space and noise are at premium. The absence of external bandgap capacitor accelerates the response time to a wake−up signal and keeps it within 40 ms, making the MC33762 as a natural candidate for portable applications. The MC33762 also hosts a novel architecture which prevents excessive undershoots in the presence of fast transient bursts, as in any bursting systems.
