ZXRE330EV-A

Overview

The ZXRE330EV-A is a precision micro-power shunt voltage reference manufactured by Diodes Incorporated. It provides a fixed output voltage of 3.3V with an initial tolerance of ±2% at +25°C. The device operates within a wide current range from 1µA to 5mA and features a low knee current characteristic, consuming only 1µA when the reference voltage can no longer be maintained. It exhibits a typical temperature coefficient of 20ppm/°C and maintains excellent stability over capacitive loads without requiring an external output capacitor.

Feature Summary

• Offers tight output voltage tolerance and sharp knee characteristics for precise regulation
• Designed for high tolerance of capacitive loads to maintain excellent stability
• Provides low output noise performance suitable for sensitive applications
• Operates effectively across a wide operating current range from 1µA to 5mA

Applications

• Battery-powered equipment
• Precision power supplies
• Portable instrumentation
• Data acquisition systems
• Low current voltage clamps

Procurement Notes

Verify component authenticity through authorized channels as the ZXRE330EV-A is designated as Not Recommended for New Design (NRND). Confirm package integrity and marking details against official datasheet specifications before integration. Ensure compliance with RoHS3 and REACH directives during procurement processes.

Selection Notes

Select this component for applications requiring a stable 3.3V reference in TO-92 packages. Consider the ±2% tolerance and 20ppm/°C temperature coefficient for circuit accuracy requirements. Evaluate the 1µA to 5mA operating range to ensure proper biasing conditions are met within the system design constraints.

Part Context

This part belongs to the ZXRE330 series of precision micro-power shunt voltage references. The 'E' suffix indicates a ±2% output voltage tolerance, distinguishing it from the 'A' variant which offers ±0.5% accuracy. The 'V' suffix denotes the TO-92 through-hole package configuration, providing a pin-for-pin compatible alternative to industry standard shunt references.

Replacement Considerations

ZXRE330AV-A is a verified substitute offering tighter ±0.5% tolerance in the same TO-92 package.
