MC33761
Ultra Low?Noise Low
Dropout Voltage Regulator
with 1.0 V ON/OFF Control
The MC33761 is an Low DropOut (LDO) regulator featuring
excellent noise performances. Thanks to its innovative design, the
circuit reaches an impressive 40 m 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 m s (in repetitive mode), making the MC33761 as a natural
candidate for portable applications.
The MC33761 also hosts a novel architecture which prevents
excessive undershoots in the presence of fast transient bursts, as in any
bursting systems.
Finally, with a static line regulation better than ?75 dB, it naturally
shields the downstream electronics against choppy lines.
