to 150 mA where it exhibits a typical 180 mV dropout. With an
incredible noise level of 25 mVRMS (over 100 Hz to 100 kHz, with a
10 nF bypass capacitor), the MC33263 represents the ideal choice for
sensitive circuits, especially in portable applications where noise
performance and space are premium. The MC33263 also excels in
response time and reacts in less than 25 ms when receiving an OFF to
ON signal (with no bypass capacitor).
without any restrictions regarding their Equivalent Series Resistance
