ZRC330F03TC

Overview

The ZRC330F03TC 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 ±3%. The device operates within a recommended current range of 20µA to 5mA and features a typical knee current of 15µA. It exhibits a temperature coefficient of 50ppm/°C and a slope resistance of 0.6Ω. The component is housed in a small outline SOT-23 package, suitable for surface mount applications.

Feature Summary

• Bandgap circuit design provides stable voltage without requiring external stabilizing capacitors
• Low knee current characteristic enables efficient operation in battery-powered systems
• Capable of withstanding transient effects and currents up to 200mA due to rugged design
• Rapid switching capability allows the device to reach stable operating conditions quickly

Applications

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

Procurement Notes

Verify that the specific suffix TC corresponds to the requested tape and reel packaging configuration. Confirm the manufacturing origin and compliance status against the latest datasheet revision DS32163 Rev. 7. Ensure the ordering part number matches the required tolerance grade and package type before finalizing procurement orders.

Selection Notes

Select this component when space-saving surface mount packages are required alongside precise voltage referencing. The low operating current makes it suitable for energy-constrained designs. Verify that the load requirements fall within the specified 20µA to 5mA range to ensure optimal performance and stability.

Part Context

This component belongs to the ZRC330 series of precision voltage references from Diodes Incorporated. The series includes variants with different tolerances and package options. The F suffix indicates the SOT-23 package style, while the 03 denotes the specific 3.3V output voltage level with ±3% accuracy.

Replacement Considerations

ZRC330F01TA (1% tolerance), ZRC330F02TA (2% tolerance). Note: ZRC330A variants (E-Line) are obsolete; SOT-23 packages are the recommended alternatives.
