Overview
The CAT8900C300TBGT3 is a precision analog voltage reference IC from onsemi, featuring a fixed output of 3V with an accuracy of ±0.08%. It operates within a supply voltage range of 2.7V to 5.5V and delivers up to 10mA output current. The device exhibits low noise (50µVp-p from 0.1Hz to 10Hz) and a temperature coefficient of 50ppm/°C. Designed for surface mount applications in SOT-23-3 packages, it supports industrial temperatures from -40°C to +85°C.
Feature Summary
- High precision voltage regulation with tight initial accuracy tolerance
- Ultra-low quiescent current consumption for power efficiency
- Low noise performance suitable for sensitive analog circuits
- Robust thermal stability across extended industrial temperature ranges
Applications
- Precision data acquisition systems
- Portable instrumentation requiring stable reference voltages
- Medical equipment signal conditioning
- Industrial process control monitoring
Procurement Notes
Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for any parameter updates. Ensure storage conditions meet manufacturer specifications to prevent degradation. Validate electrical characteristics against original specifications before integration.
Selection Notes
Evaluate output accuracy requirements against the ±0.08% specification. Consider load current needs not exceeding 10mA. Assess thermal environment compatibility with the -40°C to +85°C operating range. Review noise sensitivity for application-specific filtering needs. Compare alternative series references if tighter tolerances are required.
Part Context
Part of the CAT8900 series offering high-precision voltage references. Manufactured by onsemi focusing on intelligent power technologies. Targets automotive, industrial, cloud, medical, and IoT markets. Provides reliable voltage regulation for critical analog circuitry.
Replacement Considerations
CAT8900D300TBGT3 offers similar functionality with ±5% accuracy instead of ±0.08%. CAT8900C120TBGT3 provides a 1.2V fixed output option. Verify pinout compatibility and thermal characteristics when substituting.
