ZRC500A02STOB

Overview

The ZRC500A02STOB is a precision micropower shunt voltage reference providing a fixed 5.0V output with ±2% tolerance. It utilizes a bandgap circuit design to achieve stability without requiring an external stabilizing capacitor, remaining stable even with capacitive loads. The device operates within a recommended current range of 25μA to 5mA and supports an extended absolute maximum reverse current of 25mA. It features a low knee current of 19μA typical and achieves stable operating conditions in less than 10μs during transient response.

Feature Summary

• Bandgap circuit design ensures precision voltage reference stability without the need for external stabilizing capacitors.
• Capable of withstanding transient effects and currents up to 200mA due to rugged design and 20-volt processing capabilities.
• Provides superior switching capability allowing the device to reach stable operating conditions in microseconds.

Applications

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

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified supply chain partners. Confirm package integrity and pin configuration match the E-Line specification before integration. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent damage prior to soldering.

Selection Notes

Select this component for applications requiring a stable 5V reference in space-constrained designs using through-hole packaging. Consider the low knee current for battery-powered systems where minimal quiescent draw is critical. Evaluate thermal dissipation limits relative to ambient temperature constraints during operation.
