概览

The MC33761 is a low dropout (LDO) switching 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 MC33761 as a natural candidate for portable applications.

The MC33761 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.

  • Noise sensitive circuits: VCOs RF stages etc.

  • Fast Response Time from OFF to ON: 40ms Typical at a 200 Hz Repetition Rate
  • Ready for 1.0 V Platforms: ON with a 900 mV High Level
  • Nominal Output Current of 80 mA with a 100 mA Peak Capability
  • Typical Dropout of 90 mV @ 30 mA, 160 mV @ 80 mA
  • Ripple Rejection: 70 dB @ 1.0 kHz
  • 1.5% Output Precision @ 25°C
  • Thermal Shutdown
  • Vout Available at 2.5 V, 2.8 V, 2.9V, 3.0 V, 5.0V
  • Operating Range from -40 to +85°C
  • Dual Version is Available as MC33762
  • Pb-Free Package May be Available. The G-Suffix Denotes a Pb-Free Lead Finish.
