MCP1501T-25E/CHY

Overview

The MCP1501T-25E/CHY is a buffered voltage reference from Microchip Technology featuring a fixed output of 2.5V with an initial accuracy of ±0.1%. It operates within a supply voltage range of 2.7V to 5.5V and delivers up to 20mA of load current. The device exhibits a maximum temperature coefficient of 50 ppm/°C across the -40°C to +125°C operating range, with a typical quiescent current of 140μA.

Feature Summary

• Chopper-based amplifier architecture for low noise and reduced drift
• Integrated shutdown pin for active power management
• Curvature compensated bandgap design for high precision
• Capable of sourcing and sinking significant load currents

Applications

• Precision data acquisition systems
• High-resolution data converters
• Medical equipment applications
• Industrial controls
• Battery-powered devices

Procurement Notes

Verify the specific suffix CHY corresponds to the SOT-23-6 package configuration. Confirm AEC-Q100 automotive qualification status if required for your application. Ensure input voltage meets the minimum threshold for the 2.5V variant. Check RoHS compliance documentation for environmental requirements.

Selection Notes

Select this component when a stable 2.5V reference with moderate drive capability is needed. Consider the SOT-23-6 package for space-constrained designs. Evaluate thermal resistance if operating at high ambient temperatures or under heavy loads. Compare against buffered alternatives if higher current drive is necessary.

Part Context

This part belongs to the MCP1501 family of high-precision buffered voltage references. The series offers multiple voltage options and packages including SOIC-8 and WDFN-8. The T suffix indicates tape and reel packaging suitable for automated assembly processes.

Replacement Considerations

MCP1501-25E/SN: Alternative in SOIC-8 package. MCP1501-25E/RW: Alternative in WDFN-8 package. Verify package dimensions and pinout compatibility before substitution.
