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 mVRMS 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 ms (in repetitive mode), making the MC33761 as a natural

candidate for portable applications.

SN SUFFIX

The MC33761 also hosts a novel architecture which prevents

excessive undershoots in the presence of fast transient bursts, as in any

bursting systems.

CASE 483

Finally, with a static line regulation better than −75 dB, it naturally

shields the downstream electronics against choppy lines.
