Application Scenarios & Design Considerations

Micropower SOT-23 Low Dropout Reference Family

Alternative Part Number

  • REF3033AIDBZR --: 3.3V series voltage reference in SOT-23, similar accuracy and low dropout, pin-compatible footprint for many designs.
  • MAX6033AAUT33 --: 3.3V precision series reference in SOT-23-6, comparable temperature drift and low quiescent current.
  • ADR3533BRMZ --: 3.3V low-noise series voltage reference in MSOP-8, excellent stability and an established alternative when package adaptation is acceptable.
  • ADR363AUJZ-3.3 --: 3.3V low-noise series voltage reference in TSOT-23, similar initial accuracy and drift performance for precision applications.
