The MC33761 is an Low DropOut (LDO) regulator featuring excellent noise performances. Thanks to its innovative design, the circuit reaches an impressive 40 VRMS noise level without an external bypass capacitor. Housed in a small SOT?23 5 leads?like 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 s (in repetitive mode), making the MC33761 as a natural candidate for portable applications.
