ZRC330A01STOB

Overview

The ZRC330A01STOB is a precision micropower voltage reference utilizing bandgap circuit design to deliver a fixed 3.3V output. It operates within a recommended current range of 20μA to 5mA, with a minimum knee current of 15μA typical. The device features ±1% tolerance and maintains stability without external capacitors, even with capacitive loads. It withstands transient effects up to 200mA due to rugged 20-volt processing. Operating temperature spans -40°C to 85°C.

Feature Summary

• Bandgap design provides stable 3.3V reference without requiring external stabilizing capacitors
• Low knee current enables efficient operation in battery-powered applications
• Rugged construction allows handling of high transient currents up to 200mA
• Fast switching capability ensures rapid stabilization in microseconds

Applications

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

Procurement Notes

Verify the specific suffix 'A' corresponds to the E-Line 3-pin package configuration as defined in the official ordering information. Confirm that the '01' designation indicates the required ±1% tolerance level for the application. Ensure the component meets industrial temperature range requirements before integration into final designs.

Selection Notes

Select this component when a precise 3.3V reference is needed with tight ±1% accuracy. It is suitable for space-constrained designs using through-hole mounting. Consider the low operating current for battery life optimization. Verify compatibility with system noise requirements given the wideband noise characteristics.

Part Context

This part belongs to the ZRC330 family of precision voltage references manufactured by Diodes Incorporated. The family includes variants with different tolerances (1%, 2%, 3%) and packages (SOT23, SO8, TO92). The ZRC330 series is designed for applications requiring stable voltage references in low-power environments.

Replacement Considerations

Compatible substitutes include other ZRC330 variants with matching tolerance and package, such as ZRC330A02STOB or ZRC330A03STOB, provided the tolerance difference is acceptable. Cross-reference with other 3.3V shunt references from different manufacturers if pinout compatibility is verified.
