NCP4561
Ultra Low−Noise Low
Dropout Voltage Regulator
with 1.0 V ON/OFF Control
The NCP4561 is a Low DropOut (LDO) regulator featuring
excellent noise performances. Thanks to its innovative concept, the
circuit reaches an incredible 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 unleashes the response
time to a wake−up signal and makes it stay within 40
ms
(in repetitive
mode), pushing the NCP4561 as a natural candidate in portable
applications.
The NCP4561 also hosts a novel architecture which prevents
excessive undershoots when the regulator is the seat 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.
