MCP1501T-10E/CHY

Overview

The MCP1501T-10E/CHY is a buffered voltage reference from Microchip Technology, providing a fixed output of 1.024 V with an initial accuracy of ±0.1%. It operates within a supply voltage range of 1.65 V to 5.5 V and maintains a maximum temperature coefficient of 50 ppm/°C across the -40°C to +125°C operating range. The device features a typical operating current of 140 μA and can source or sink up to 20 mA. It utilizes a chopper-based amplifier architecture for low noise and drift.

Feature Summary

• Buffered output capable of sourcing and sinking 20 mA load currents
• Chopper-based amplifier architecture reduces drift and offsets
• Integrated shutdown pin for active power management
• Curvature compensated bandgap design for high precision

Applications

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

Procurement Notes

Verify the specific suffix CHY against official datasheets to confirm package type and tape-and-reel specifications. Ensure the ordering code matches the required automotive qualification status if applicable. Confirm that the input voltage requirements align with the minimum threshold for the 1.024V variant before finalizing procurement.

Selection Notes

Select this component when a stable 1.024 V reference is required with moderate drive capability. The SOT-23-6 package offers a compact footprint suitable for space-constrained designs. Consider the 50 ppm/°C temperature coefficient for environments with significant thermal variations. Verify that the 140 μA quiescent current meets system power budget constraints.

Part Context

This part belongs to the MCP1501 family of high-precision buffered voltage references. The series includes multiple voltage options ranging from 1.024 V to 5.000 V. The T suffix indicates a tape and reel packaging format, while CHY specifies the specific package and shipping configuration defined by the manufacturer.

Replacement Considerations

The MCP1501-10E/SN serves as a direct functional substitute in an SOIC-8 package. Other variants within the MCP1501 family offer different fixed output voltages but share identical electrical characteristics and pinouts.
