CMPWR101 - 250mA SmartOR Regulator

Description

regulator that delivers up to 250 mA of load current at a fixed 3.3 V output.

An internal threshold level (typically 4.1 V) is used to prevent the regulator from being operated below dropout voltage.

Features

  • Automatic Detection of VCC Input Supply.
  • Glitch.
  • Free Output During Supply Transitions.
  • Built.
  • In Hysteresis During Supply Selection.
  • 250 mA Output Maximum Load Current.
  • Fully Integrated VAUX Switch.
  • Overload Current Protection.
  • Short Circuit Current Protection.
  • Operates from Either VCC or VAUX.
  • 8.
  • Pin SOIC Package.
  • These Devices are Pb.
  • Free and are RoHS Compliant.

CMPWR101 250 mA SmartORt Regulator with VAUX Switch Product Description The ON Semiconductor’s SmartORt CMPWR101 is a low dropout regulator that delivers up to 250 mA of load current at a fixed 3.3 V output. An internal threshold level (typically 4.1 V) is used to prevent the regulator from being operated below dropout voltage. The device continuously monitors the input supply and will automatically disable the regulator when VCC falls below the threshold level. When the regulator is disabled, a low impedance, fully integrated switch is enabled which allows the output to be directly powered from an auxiliary 3.3 V supply. When VCC is restored to a level above the select threshold, the low impedance switch is disabled and the regulator is once again enabled.
