onsemi NCP4561
The NCP4561 is a Low DropOut (LDO) regulator featuring excellent noise performances. 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.| Part No. | NCP4561 |
