ZRC500A03

Overview

The ZRC500A03 is a precision micropower voltage reference providing a fixed 5.0V output with ±3% initial accuracy. It utilizes a bandgap circuit design and operates within an industrial temperature range of -40°C to +85°C. The device requires no external stabilizing capacitor and maintains stability with capacitive loads. Recommended operating current ranges from 25μA to 5mA, with a typical temperature coefficient of 30ppm/°C and a wideband noise voltage of 105μVrms.

Feature Summary

Bandgap circuit design for stable voltage reference without external capacitors
Capacitive load stability and fast transient response in microseconds
Low knee current operation suitable for battery-powered applications
Robust design withstands transient effects and high currents

Applications

Battery powered and portable equipment
Instrumentation
Test equipment
Metering and measurement systems

Procurement Notes

Verify the specific package suffix required for the application, as the ZRC500 series includes multiple variants such as SOT23, SO8, and E-Line configurations. Confirm that the ±3% tolerance aligns with system requirements. Ensure the operating current remains within the recommended 25μA to 5mA range for optimal performance. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a fixed 5.0V reference with moderate precision is needed in space-constrained designs. The E-Line package offers through-hole mounting options. Consider the ±3% tolerance and 30ppm/°C temperature coefficient against stricter requirements. Evaluate the low knee current for efficiency in battery-operated circuits where quiescent power consumption is critical.

Part Context

The ZRC500A03 belongs to the ZRC500 family of precision voltage references manufactured by Diodes Incorporated. This series provides various tolerance levels and package styles to accommodate different PCB layout and precision needs. The A03 designation specifically indicates the E-Line package variant with 3% accuracy.
