MC33762: Dual Low Noise, Low Dropout Linear Voltage Regulator with 1.0 V ON/OFF Control
The MC33762 is a low dropout (LDO) linear voltage regulator featuring excellent noise performances. Thanks to its innovative design, the circuit reaches an impressive 40uVRMS noise level without an external bypass capacitor. Housed in a small SOT-23 5 leads-like package, this LDO represents the ideal designer's choice when space and noise are at premium. The absence of external bandgap capacitor accelerates the response time to a wake-up signal and keeps it within 40us (in repetitive mode), making the MC33762 as a natural candidate for portable applications. The MC33762 low dropout (LDO) linear voltage regulator also hosts a novel architecture which prevents excessive undershoots in the presence of fast transient bursts, as in any bursting systems. Finally, with a static line regulation better than -75dB, it naturally shields the downstream electronics against choppy lines.
