ZRC500A01

Overview

The ZRC500A01 is a precision micropower voltage reference providing a fixed 5.0V output with ±1% initial accuracy. It utilizes a bandgap circuit design and operates within an industrial temperature range of -40°C to +85°C. The device requires no external stabilizing capacitor and maintains stability with capacitive loads. Recommended operating current ranges from 25μA to 5mA, with a typical knee current of 19μA. Key electrical parameters include a typical temperature coefficient of 30ppm/°C, a slope resistance of 0.4Ω, and wideband noise of 105μVrms.

Feature Summary

• Bandgap circuit design delivering stable 5.0V reference without external capacitors
• Low knee current enabling efficient operation in battery-powered applications
• Rugged construction withstands transient effects and currents up to 200mA
• Fast transient response achieving stable conditions in less than 10μs

Applications

• Battery powered and portable equipment
• Instrumentation systems

Procurement Notes

Verify the specific package suffix for the ZRC500A01 variant, as the datasheet indicates E-Line configurations (e.g., A, R, Y) exist. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing standards. Ensure the ordering information matches the exact tolerance and package style required for your circuit design before finalizing procurement.

Selection Notes

Select this component when space-saving surface mount or through-hole options are needed alongside high precision. The ±1% tolerance makes it suitable for applications requiring tight voltage accuracy. Consider the low operating current for power-sensitive designs, while noting the rugged design supports higher transient currents if necessary for robust system performance.

Part Context

The ZRC500 series includes various packages such as SOT23, SO8, and E-Line styles. The ZRC500A01 specifically denotes the E-Line package with 1% tolerance. Other variants like ZRC500F01 offer similar electrical characteristics in different form factors. This family provides flexibility for both PCB space constraints and through-hole mounting requirements.
