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 μVRMS (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 μs when receiving an OFF to ON signal (with no bypass capacitor)
