Application Scenarios & Design Considerations

Low-Voltage Reference

Alternative Part Number

  • LM285Z-2.5 --: 2.5V shunt voltage reference in TO-92, widely available and a common substitute for the MC1403D 2.5V reference in many designs.
  • ADR4525BRZ --: High-precision 2.5V series voltage reference with low drift and low noise, suitable where improved accuracy over the MC1403D is needed.
  • REF5025AID --: 2.5V series voltage reference with good initial accuracy and low temperature drift, a practical drop-in style alternative for 2.5V reference applications.
  • LM313H --: Precision voltage reference with similar 2.5V output and low temperature drift, widely used as a direct functional substitute.
  • AD580 --: 2.5V bandgap voltage reference offering comparable accuracy and stability for precision reference applications.
  • REF02 --: 5V precision voltage reference with excellent long-term stability, suitable when a higher reference voltage is acceptable.
