CAT8900B260TBGT3

Overview

The CAT8900B260TBGT3 is a precision series voltage reference manufactured by onsemi, housed in a SOT-23-3 surface-mount package. It provides a fixed output of 2.6 V with a tolerance of ±0.04%. The device operates within an input voltage range of 2.7 V to 5.5 V and draws a supply current of 800 nA. It features a temperature coefficient of 50 ppm/°C and low noise of 50 µVp-p from 0.1 Hz to 10 Hz. The component supports a maximum load current of 10 mA and functions reliably across a junction temperature range of -40°C to +85°C.

Feature Summary

• Delivers high-precision fixed voltage output with tight initial tolerance for accurate analog circuitry.
• Utilizes a series reference architecture to maintain stability under varying load conditions.
• Designed for ultra-low power consumption suitable for battery-operated portable applications.

Applications

• Precision data acquisition systems requiring stable reference voltages
• Battery-powered instrumentation and measurement devices
• High-resolution analog-to-digital converter (ADC) references

Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct output voltage and tolerance grades. Confirm RoHS compliance status through manufacturer documentation prior to integration. Check for obsolete status or lifecycle changes as availability may be restricted. Ensure thermal management aligns with the specified operating temperature range during PCB layout.

Selection Notes

Select this component when a fixed 2.6 V reference with high accuracy is required in a compact SOT-23 form factor. Consider the low quiescent current for energy-efficient designs. Evaluate the temperature coefficient requirements against application environmental conditions. Compare noise specifications if low-frequency interference is a critical design constraint.

Part Context

This part belongs to the CAT8900 family of precision voltage references from onsemi. The family offers various fixed output voltages and tolerance grades within the same SOT-23-3 footprint. These devices are designed to replace older discrete reference solutions, providing improved performance and space efficiency in modern power management integrated circuits.

Replacement Considerations

CAT8900D260TBGT3: Offers similar functionality but with different initial tolerance specifications. Verify that the tolerance grade meets the system accuracy requirements before substitution.
