ZRC500A01STOB

Overview

The ZRC500A01STOB is a precision micropower voltage reference providing a fixed 5.0V output with ±1% initial accuracy. It utilizes a bandgap circuit design to ensure stability without requiring an external stabilizing capacitor, even with capacitive loads. The device operates within a recommended current range of 25μA to 5mA and supports an absolute maximum reverse current of 25mA. It features a typical temperature coefficient of 30ppm/°C and achieves stable operating conditions in less than 10μs during transient responses.

Feature Summary

• Bandgap circuit design delivers precise 5.0V reference output
• Intrinsic stability eliminates the need for external compensation capacitors
• Low knee current enables efficient operation in battery-powered systems
• Rugged construction withstands high transient currents up to 200mA

Applications

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

Procurement Notes

Verify the specific package suffix against official documentation, as standard part numbers may not explicitly include the STOB designation in all manufacturer listings. Confirm availability status, as this component may be discontinued or subject to long lead times. Ensure the selected variant matches the required tolerance and package type for your specific PCB layout and performance needs.

Selection Notes

Select this component when space-saving surface mount or through-hole E-Line packages are required alongside high precision. The low operating current makes it suitable for power-sensitive designs. Consider the ±1% tolerance for applications demanding tight voltage accuracy. Evaluate the thermal management requirements based on the specific package power dissipation ratings provided in the datasheet.
