... Figure 29 shows the stability region for a range of operating conditions and ESR values. Noise Decoupling The NCP500 is a low noise regulator without the need of an external bypass capacitor. It typically reaches a noise level of 50 mVRMS overall noise between 10 Hz and 100 kHz. The classical bypass capacitor impacts the start up phase of standard LDOs ...
