Housed in a SOT23–L package, the MC33263 delivers up to  
150 mA where it exhibits a typical 180 mV dropout. With an  
incredible noise level of 25 VRMS (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 s when receiving an OFF to  
ON signal (with no bypass capacitor).  
Thanks to a novel concept, the MC33263 accepts output capacitors  
without any restrictions regarding their Equivalent Series Resistance  
(ESR) thus offering an obvious versatility for immediate implementation.  
With a typical DC ripple rejection better than –90 dB (–70 dB @  
1 kHz), it naturally shields the downstream electronics against choppy  
power lines.
