ZRC250A03STZ

Overview

The ZRC250A03STZ is a precision micropower voltage reference providing a fixed output of 2.5V using bandgap circuit design. It operates within an industrial temperature range of -40°C to +85°C and features a typical temperature coefficient of 30ppm/°C. The device requires no external stabilizing capacitor and maintains stability with capacitive loads. Recommended operating current ranges from 20µA to 5mA, with absolute maximum ratings supporting up to 25mA reverse current and transient effects up to 200mA.

Feature Summary

• Bandgap circuit design achieves precise 2.5V reference without requiring external stabilizing capacitors
• Low knee current characteristic enables stable operation in low power and battery-powered applications
• Rugged design withstands transient effects and currents up to 200mA while maintaining superior switching capability

Applications

• Battery powered and portable equipment
• Instrumentation
• Test equipment

Procurement Notes

Verify the specific package suffix against official documentation to confirm pin configuration and mechanical dimensions. Ensure the selected variant matches the required tolerance level for the intended circuit design. Confirm compliance with relevant environmental standards before final procurement decisions.

Selection Notes

Select this component when space-saving surface mount or through-hole packages are required alongside high precision. Consider the low knee current specification for battery-operated designs where minimizing quiescent consumption is critical. Evaluate the ±3% tolerance against application requirements for voltage accuracy.
