ZR285N802TA

Overview

The ZR285N802TA is a precision micropower voltage reference providing a nominal output of 2.5 volts, manufactured by Diodes Incorporated. It utilizes a bandgap circuit design to deliver stable performance without requiring an external stabilizing capacitor. The device operates within a recommended current range of 20 μA to 20 mA and features a typical temperature coefficient of 30 ppm/°C. It is housed in an SO-8 surface mount package with a ±2% initial accuracy tolerance.

Feature Summary

• Bandgap circuit design ensures precise voltage regulation
• Capacitor-free stability for simplified circuit implementation
• Low knee current operation suitable for battery-powered systems
• Robust transient handling capability up to 200mA

Applications

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

Procurement Notes

Verify the specific suffix N8 confirms the SO-8 package configuration. Confirm the TA suffix aligns with the required tape and reel quantity or packaging format. Ensure the component meets RoHS compliance requirements if applicable to the target assembly process. Cross-reference the datasheet revision date against manufacturing lot dates for quality assurance.

Selection Notes

Select this component when space-saving surface mount integration is required alongside high precision. The low operating current makes it ideal for energy-constrained designs. Verify that the load conditions remain within the specified 20μA to 20mA range for optimal performance. Consider the thermal dissipation limits if operating near maximum ratings.

Part Context

This part belongs to the ZR285 series of micropower voltage references. The series offers various tolerances and packages, including SOT23, SO8, and E-Line styles. The ZR285N802 variant specifically denotes the 2% tolerance version in the SO-8 package, providing a compact solution for industrial temperature range applications.

Replacement Considerations

Direct pin-to-pin replacements should maintain the 2.5V output and SO-8 footprint. Verify that substitute components offer comparable temperature coefficients and noise specifications. Ensure the alternative supports the same minimum operating current to prevent instability.
