MC1403BDR2G

Overview

The MC1403BDR2G is a series voltage reference integrated circuit manufactured by onsemi. It provides a fixed output voltage of 2.5V with a tolerance of ±1%. The device operates within an input voltage range of 4.5V to 40V and draws a supply current of 1.5mA. It features a temperature coefficient of 40ppm/°C and can deliver an output current of up to 10mA. The component is housed in an 8-SOIC package, supports surface mount installation, and functions reliably across a temperature range of 0°C to 70°C.

Feature Summary

• Provides a stable series voltage reference output
• Maintains tight voltage tolerance for precision applications
• Operates over a wide input voltage range

Applications

• Precision analog-to-digital converter references
• Voltage regulation circuits requiring stable reference
• Measurement instrumentation power supplies

Procurement Notes

Verify the specific suffix 'B' indicates the ±1% tolerance grade when ordering. Confirm the 'DR2G' suffix corresponds to the tape and reel packaging format required for automated assembly processes. Ensure the operating environment remains within the specified commercial temperature limits to maintain performance specifications.

Selection Notes

Select this component when a fixed 2.5V reference is required with high accuracy. Consider the ±1% tolerance against application requirements. Evaluate the 1.5mA supply current for power efficiency constraints. Verify that the 8-SOIC package fits the PCB layout and thermal management design.

Part Context

This part belongs to the MC1403 family of voltage references from onsemi. It serves as a foundational component for establishing precise voltage levels in mixed-signal systems. The device complements other logic and power management ICs by providing a clean, stable reference potential independent of supply fluctuations.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar voltage and tolerance specifications. Verify that any substitute maintains the 8-SOIC footprint and meets the required temperature and current capabilities.
