ZRC400A02STOA

Overview

The ZRC400A02STOA is a precision micropower voltage reference providing a nominal output of 4.096V, manufactured by Diodes Incorporated. It utilizes a bandgap circuit design to achieve stable performance without requiring an external stabilizing capacitor. The device operates within a recommended current range of 23μA to 5mA and supports an absolute maximum reverse current of 25mA. It features a typical temperature coefficient of 30ppm/°C and maintains stability with capacitive loads. The component is housed in an E-Line package with a 2% initial tolerance.

Feature Summary

• Bandgap circuit design ensures precision voltage reference stability
• Operates without the need for external stabilizing capacitors
• Capable of withstanding transient effects and high currents up to 200mA
• Rapid stabilization reaching operating conditions in microseconds

Applications

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

Procurement Notes

Verify the specific package suffix against the ordering information table to confirm pin configuration and tolerance. The 'A' suffix denotes a standard 3-pin E-Line package, while other variants exist. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure operating current remains within the specified 23μA to 5mA range for optimal performance.

Selection Notes

Select this component when space-saving through-hole designs are required alongside low power consumption needs. The device is suitable for applications demanding high stability without external compensation components. Consider the 2% tolerance variant if tighter accuracy specifications are not critical. Evaluate the rugged design benefits for environments subject to electrical transients.
