ZR40401R25

Overview

The ZR40401R25 is a precision micropower voltage reference providing a nominal output of 2.5 volts with an initial accuracy of 1%. It utilizes a bandgap circuit design and operates within a recommended current range of 60 µA to 15 mA, making it suitable for low-power applications. The device features a typical temperature coefficient of 30 ppm/°C and maintains stability without requiring an external stabilizing capacitor. It is housed in an E-Line, 3-pin (TO92) package.

Feature Summary

• Bandgap circuit design ensures stable voltage output without the need for external capacitors.
• Capable of withstanding transient effects and currents up to 200mA due to rugged construction.
• Achieves stable operating conditions rapidly with a transient response time of less than 10 microseconds.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'R' corresponds to the E-Line, 3-pin package configuration before procurement. Confirm that the 1% tolerance variant matches the required precision for the target application. Ensure the component meets industrial temperature range specifications if deployed in varying thermal environments.

Selection Notes

Select this component when space-saving through-hole packaging is preferred over surface-mount options. It is appropriate for designs requiring high stability without external compensation components. Consider the 60 µA minimum operating current constraint to ensure proper regulation during low-load conditions.
