CAT8900A250TBGT3

Overview

The CAT8900A250TBGT3 is a series precision voltage reference IC manufactured by onsemi. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.02%. The device operates within an input voltage range of 2.7V to 5.5V and delivers a maximum output current of 10 mA. It features a low temperature coefficient of 50 ppm/°C and consumes a supply current of 800 nA. The component is housed in a SOT-23-3 surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Provides high-precision fixed voltage output with tight initial accuracy tolerance
• Features ultra-low quiescent current consumption for power-sensitive applications
• Utilizes compact surface-mount packaging for space-constrained designs

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• Battery-powered instrumentation requiring low power consumption

Procurement Notes

Verify product status as the component may be obsolete or discontinued. Confirm availability through authorized distributors, noting potential supply restrictions. Ensure compatibility with existing PCB footprints and validate thermal performance within the specified operating temperature range before integration.

Selection Notes

Select this component when high initial accuracy and low drift are critical. Compare against other CAT8900 variants based on required output voltage levels. Consider the SOT-23-3 package constraints and ensure the 10 mA load capability meets circuit demands while maintaining low power consumption requirements.

Part Context

This part belongs to the CAT8900 series of precision voltage references from onsemi. The series offers various fixed output voltages with similar low-power characteristics. The 'A' suffix typically denotes specific accuracy grades, while 'D' indicates different tolerances within the same family architecture.

Replacement Considerations

Check for direct pin-compatible substitutes within the CAT8900 series offering different voltage outputs. Verify if newer generation references from onsemi or competitors maintain equivalent accuracy and current specifications.
