ZRC250F03TC

Overview

The ZRC250F03TC is a precision micropower voltage reference providing a nominal output of 2.5 volts, manufactured by Diodes Incorporated. It utilizes a bandgap circuit design and operates within an industrial temperature range from -40°C to +85°C. The device features a typical temperature coefficient of 30 ppm/°C and maintains stability without requiring an external stabilizing capacitor. Recommended operating current ranges from 20 μA to 5 mA, with a low knee current of 15 μA typical. The unit is housed in a small outline SOT-23 package.

Feature Summary

• Bandgap circuit design for stable voltage generation
• Capacitor-free operation with capacitive load stability
• Low knee current suitable for battery-powered applications
• Rugged design capable of withstanding transient effects

Applications

• Battery powered equipment
• Portable equipment
• Instrumentation
• Test equipment

Procurement Notes

Verify the specific suffix 'TC' against official manufacturer documentation, as standard datasheets list 'TA' for tape-and-reel packaging. Confirm that the component matches the required ±3% tolerance and SOT-23 form factor. Ensure compatibility with the specified operating current range and temperature coefficients before procurement.

Selection Notes

Select this component when space-saving surface mount packages are required alongside precise voltage referencing. It is appropriate for designs prioritizing low power consumption due to its micropower characteristics. Consider the ±3% initial accuracy and 30 ppm/°C temperature drift for high-precision analog signal conditioning tasks.

Part Context

This part belongs to the ZRC250 series of precision voltage references. The series offers various tolerance options including ±1%, ±2%, and ±3%. The F suffix indicates the SOT-23 package type. This family is designed for applications where physical size constraints and low power usage are critical factors.

Replacement Considerations

Datasheet notes indicate that all ZRC250A variants (E-Line) are obsolete. The closest alternative for these legacy parts is the standard SOT-23 package configuration found in the current ZRC250 lineup.
