ZRB500F03TA

Overview

The ZRB500F03TA is a precision micropower voltage reference IC manufactured by Diodes Incorporated. It utilizes a bandgap circuit design to provide a stable 5.0V output with an initial accuracy of ±3%. The device operates within a recommended current range of 50µA to 15mA and features a typical temperature coefficient of 15ppm/°C, with a maximum of 50ppm/°C. It supports a maximum input voltage of 20V and functions reliably in the industrial temperature range of -40°C to +85°C. The component is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Bandgap circuit design ensures stable voltage output without requiring external capacitors
• Capable of withstanding transient effects and high currents up to 200mA due to rugged 20V processing
• Rapid stabilization capability allows the device to reach stable operating conditions in microseconds

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 tolerance suffix 'F' corresponds to the required ±3% accuracy for your design. Confirm that the SOT-23-3 package dimensions align with your PCB footprint layout. Ensure the operating environment remains within the specified -40°C to +85°C range to maintain performance specifications. Check for any recent product change notices regarding manufacturing sites or materials.

Selection Notes

Select this component when space constraints necessitate a small outline surface mount package like SOT-23. It is suitable for low-power applications where the operating current falls between 50µA and 15mA. Consider this part if a fixed 5.0V reference is needed with moderate precision requirements. Evaluate the thermal management capabilities if the device will handle currents approaching the maximum limits.

Part Context

This part belongs to the ZRB500 series of precision voltage references from Diodes Incorporated. The series includes variants with different tolerances, such as ±1% and ±2%, identified by suffixes 'O1' and 'O2'. The 'F03' designation specifically indicates the ±3% tolerance version packaged in SOT-23. Other obsolete packages in this family include E-Line and SO-8 configurations.

Replacement Considerations

Direct substitutes within the same series include ZRB500F01TA (±1% tolerance) and ZRB500F02TA (±2% tolerance). These parts share identical pinouts and packaging but offer tighter voltage accuracy. Verify that the application can accommodate the specific tolerance levels provided by these alternatives.
