SG1503Y-883B

Overview

The SG1503Y-883B is a precision series voltage reference IC manufactured by Microchip Technology. It provides a fixed output voltage of 2.5 V with an initial accuracy of 1%. The device operates within a temperature range of -55°C to +125°C and features a temperature coefficient of 10 ppm/°C. It supports a maximum output current of 10 mA and accepts input voltages up to 40 V. The component is housed in an 8-pin CDIP package designed for through-hole mounting.

Feature Summary

• Provides stable precision voltage reference performance suitable for high-reliability applications
• Features low temperature coefficient for consistent output across wide thermal ranges
• Designed for robust operation in military and aerospace environments

Applications

• Military avionics systems requiring certified components
• Aerospace instrumentation and control circuits
• High-reliability data acquisition systems

Procurement Notes

Verify the specific suffix '883B' confirms MIL-STD-883 compliance and screening requirements. Confirm lot traceability and certification documents are available from authorized distributors. Ensure the ordering information matches the exact package style and electrical specifications required for your design.

Selection Notes

Select this component when a fixed 2.5 V reference with strict accuracy and thermal stability is required. Consider the through-hole CDIP package constraints and input voltage limits. Evaluate if the 10 mA output current meets the load requirements of the reference circuit.

Part Context

This part belongs to the Microchip SG1503 family of precision voltage references. The '883B' suffix typically indicates compliance with MIL-STD-883 standards, distinguishing it from commercial variants. It serves as a critical reference element in analog signal chains where long-term stability and noise performance are paramount.

Replacement Considerations

Check for direct cross-reference parts with identical pinouts and electrical specs. Verify that any substitute also meets the required environmental and reliability standards if used in regulated industries.
