MCP1541T-I/TT

Overview

The MCP1541T-I/TT is a precision voltage reference providing a nominal output of 4.096V in a SOT-23-3 package. It features an initial accuracy of ±1% and a temperature drift of ±50 ppm/°C. The device operates with a maximum input current of 100 µA at +25°C and supports an output current drive of ±2 mA. Input voltage ranges from 4.3V to 5.5V, while the operating temperature range spans -40°C to +85°C.

Feature Summary

• Utilizes advanced CMOS circuit design combined with EPROM trimming for high stability.
• Provides low quiescent current consumption suitable for battery-powered applications.
• Offers superior time and temperature stability compared to traditional Zener techniques.

Applications

• Battery-powered systems
• Handheld instruments
• Data acquisition systems
• Precision power supplies
• D/A Converters (DACs)

Procurement Notes

Verify that the ordering suffix 'TT' corresponds to the Tape and Reel packaging format as specified in the Microchip Product Identification System. Confirm the 'I' designation indicates the Industrial Temperature Range (-40°C to +85°C). Ensure the component matches the MCP1541 variant for the 4.096V output requirement rather than the MCP1525.

Selection Notes

Select this component when a stable 4.096V reference is required in a compact SOT-23-3 footprint. It is appropriate for designs needing ±1% initial accuracy and low power consumption. Ensure the input supply voltage remains within the 4.3V to 5.5V range to maintain specified line regulation and performance characteristics.

Part Context

This part belongs to the MCP1525/41 family of precision voltage references manufactured by Microchip Technology. The series includes the MCP1525 (2.5V) and MCP1541 (4.096V) variants. Both share identical electrical characteristics and package options, differing only in their trimmed output voltage levels.
