MCP1501T-50E/CHY

Overview

The MCP1501T-50E/CHY is a buffered voltage reference providing a fixed 5.000 V output with 0.1% initial accuracy and a maximum temperature coefficient of 50 ppm/°C across the -40°C to +125°C range. It operates on an input supply from 5.2 V to 5.5 V, drawing a typical current of 140 μA. The device features low noise (30 µVRMS) and can source or sink up to 20 mA. Packaged in a 6-lead SOT-23, it includes a shutdown pin for power management.

Feature Summary

• High-precision bandgap architecture utilizing chopper-based amplifiers to minimize drift and offset errors.
• Capable of sourcing and sinking 20 mA load currents while maintaining stable regulation.
• Integrated digital shutdown control allows for active low-power mode operation.

Applications

• Precision data acquisition systems
• High-resolution analog-to-digital converter references
• Electric vehicle battery management systems

Procurement Notes

Verify the specific suffix CHY corresponds to the required tape-and-reel packaging configuration. Confirm that the minimum operating voltage of 5.2 V aligns with the system power rail, as this variant requires a higher headroom than lower voltage options. Ensure the design accommodates the thermal characteristics of the SOT-23 package under expected load conditions.

Selection Notes

Select this component when a precise 5.0 V reference is required with high current drive capabilities. It is suitable for designs needing automotive qualification via AEC-Q100 standards. Consider the 5.2 V minimum input requirement to ensure proper dropout performance. Compare against other MCP1501 variants if different output voltages or package types better suit the board layout constraints.

Part Context

This part belongs to the MCP1501 family of high-precision buffered voltage references manufactured by Microchip Technology. The series offers multiple fixed output voltage options ranging from 1.024 V to 5.0 V. The T-50 designation specifically indicates the 5.000 V output version housed in the compact 6-lead SOT-23 surface-mount package.

FAQ

Is the MCP1501T-50E/CHY qualified for automotive applications?

Yes, the 6-Lead SOT-23 package version of the MCP1501 is AEC-Q100 qualified for automotive use.

What is the function of the SHDN pin?

The SHDN pin is a digital input that places the device into a low-current shutdown state when driven low, effectively disabling the output.
