MC33761
Ultra LowNoise 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 VRMS noise level
without
an
external bypass capacitor. Housed in a small SOT23 5 leadslike
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 wakeup signal and keeps it within
40 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.
