  • Fixed output voltage of 2.3V
  • Output current rating of 150mA
  • Maximum input voltage of 5.25V
  • Dropout voltage specification of 0.38V @ 150mA
  • Quiescent current of 60 µA
  • PSRR of 75dB (1kHz)
  • Over Current protection feature
  • Operating temperature range of -40°C ~ 85°C
  • 4-XDFN Exposed Pad package configuration
  • Surface mount mounting type
  • Active product status
  • RoHS3 compliance

Parts meeting all these criteria are classified as direct parametric equivalents and may be substituted without circuit redesign.
