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.
Additionally, thermal shutdown and short–circuit protection
provide the final product with a high degree of ruggedness.
