ZRC400A03STOB

Overview

The ZRC400A03STOB 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 high stability without requiring an external stabilizing capacitor. The device operates within a recommended current range of 23μA to 5mA and supports an extended operating current up to 25mA. It features a typical temperature coefficient of 30ppm/°C and maintains stability with capacitive loads. The component is housed in an E-Line (TO-92) package with a ±3% tolerance.

Feature Summary

• Bandgap circuit design ensures stable voltage output without the need for external stabilizing capacitors
• Capable of withstanding transient effects and currents up to 200mA due to rugged 20-volt processing
• Provides superior switching capability reaching stable operating conditions in less than 10 microseconds
• Low knee current characteristic allows operation down to 18μA typical

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact package type and pin configuration. The 'R' suffix indicates an E-Line 3-pin reversed package variant. Confirm that the ±3% tolerance aligns with application requirements. Ensure the operating environment remains within the specified -40°C to 85°C industrial temperature range for optimal performance.

Selection Notes

Select this component for applications requiring a precise 4.096V reference with low power consumption. The wide operating current range from 23μA to 5mA makes it suitable for battery-powered designs. Consider the ±3% tolerance and 30ppm/°C temperature coefficient when designing circuits sensitive to voltage drift. The TO-92 package offers through-hole mounting options for space-constrained or legacy board layouts.
