ZR404005F25TA

Overview

The ZR404005F25TA is a precision micropower shunt voltage reference providing a fixed output of 2.5V with an initial accuracy of ±0.5%. It utilizes a bandgap circuit design and operates within a recommended current range of 60µA to 15mA, with absolute maximum ratings supporting up to 25mA reverse current. The device features a typical temperature coefficient of 30ppm/°C and a slope resistance of 0.4Ω. It is housed in a small outline SOT-23 package (suffix F) and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Bandgap circuit design ensures stable voltage output without requiring external stabilizing capacitors.
• Capable of withstanding transient effects and currents up to 200mA due to rugged 20-volt processing.
• Provides superior switching capability with stable operating conditions reached in 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 tolerance suffix '05' for ±0.5% accuracy and package suffix 'F' for SOT-23 configuration against project requirements. Confirm that the industrial temperature range (-40°C to +85°C) aligns with environmental specifications. Ensure input voltages remain within safe limits to prevent exceeding the 25mA absolute maximum rating during operation.

Selection Notes

Select this component when space-saving surface mount packaging is required alongside high precision. The low minimum operating current of 60µA makes it suitable for battery-powered designs where quiescent power consumption must be minimized. Verify that the load capacitance does not compromise stability, although the device is designed to handle capacitive loads effectively.
