ZRB500A01

Overview

The ZRB500A01 is a precision micropower voltage reference utilizing bandgap circuit design to deliver a fixed 5.0V output. It offers ±1% initial accuracy with a typical temperature coefficient of 15ppm/°C. The device operates within an industrial temperature range of -40°C to +85°C and supports currents from 50µA to 15mA. It features transient response stability in under 10µs, withstands up to 200mA transients, and requires no external capacitor for stability.

Feature Summary

• Capable of withstanding transient effects and high currents up to 200mA
• Superior switching capability ensures rapid stabilization in microseconds
• Utilizes green molding compound free of bromine and antimony

Applications

• Battery powered and portable equipment
• Metering and measurement systems
• Instrumentation and test equipment
• Data acquisition systems
• Precision power supplies

Procurement Notes

Verify the specific suffix (e.g., F01TA) against current availability as older E-Line variants are obsolete. Confirm RoHS compliance status and check for active manufacturing support before finalizing procurement plans.

Selection Notes

Select this component for applications requiring precise 5V references in space-constrained designs using SOT23 packages. Ensure operating current remains between 50µA and 15mA for optimal performance and verify thermal requirements within the specified industrial range.

Part Context

This part belongs to the ZRB500 series of precision voltage references manufactured by Diodes Incorporated. The series includes variants with different tolerances and package types, such as SOT23 and through-hole options, designed for low-power and battery-operated electronic systems.

Replacement Considerations

E-Line 3-pin variants like ZRB500A01 are obsolete. The closest alternative is the SOT23 package version, specifically ZRB500F01TA.
