ZRC330F02TA

Overview

The ZRC330F02TA is a precision micropower voltage reference IC manufactured by Diodes Incorporated. It utilizes a bandgap circuit design to provide a stable 3.3V output with an initial tolerance of ±2%. The device operates within a recommended current range of 20µA to 5mA and features a low knee current of 15µA typical. It exhibits a temperature coefficient of 50ppm/°C and a slope resistance of 0.6Ω typical. The component is housed in a small outline SOT-23 package, suitable for space-constrained applications.

Feature Summary

• Bandgap circuit design provides stable voltage without requiring external stabilizing capacitors
• Low knee current characteristic enables operation at minimal bias currents
• Capable of withstanding transient effects and high currents up to 200mA due to rugged design
• Superior switching capability allows the device to reach stable operating conditions rapidly

Applications

• Battery powered and portable equipment
• Metering and measurement systems
• Instrumentation
• Test equipment
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix 'F02' corresponds to the required ±2% tolerance level when sourcing this component. Confirm that the SOT-23 package variant aligns with your PCB footprint requirements. Ensure the procurement channel is authorized to guarantee product authenticity and compliance with RoHS standards as specified by the manufacturer.

Selection Notes

Select the ZRC330F02TA when a fixed 3.3V reference with ±2% accuracy is required. This model is appropriate for designs prioritizing low power consumption and compact form factors. Consider the 20µA minimum operating current when designing bias networks. Evaluate the 50ppm/°C temperature coefficient against your system's thermal stability needs.

Part Context

This component belongs to the ZRC330 series of precision voltage references from Diodes Incorporated. The series includes variants with different tolerances, such as ±1% and ±3%, all sharing the same core bandgap architecture and SOT-23 packaging. The F02 designation specifically identifies the version with 2% initial accuracy.

Replacement Considerations

ZRC330F01TA (±1% tolerance) and ZRC330F03TA (±3% tolerance). These parts share identical pinouts and electrical characteristics except for initial accuracy.
