LT1460KCS3-3.3#TRPBF

Voltage Reference Overview

The LT1460KCS3-3.3#TRPBF is a micropower bandgap voltage reference in a 3-lead SOT-23 package, manufactured by Analog Devices Inc. It provides a fixed output of 3.3V with an initial accuracy of ±0.5%. The device operates within a commercial temperature range of 0°C to 70°C and features a maximum temperature coefficient of 50ppm/°C. Supply current is typically 180µA, with a minimum input-output differential of 0.9V. It supports up to 20mA sourcing current without requiring an output compensation capacitor.

Voltage Reference Feature Summary

• Utilizes curvature compensation and trimmed thin-film resistors for high precision
• Capable of supplying up to 20mA load current
• Stable with capacitive loads without external compensation
• Protected against reverse battery connection damage

Voltage Reference Applications

• Handheld Instruments
• Precision Regulators
• A/D and D/A Converters
• Power Supplies
• Hard Disk Drives

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging. Confirm the K grade corresponds to the required ±0.5% accuracy and 50ppm/°C drift specifications. Ensure the commercial temperature range (0°C to 70°C) meets system requirements rather than industrial or high grades.

Voltage Reference Selection Notes

Select this component when board space is limited due to the small SOT-23 footprint. It is suitable for applications requiring low supply current compared to shunt references. Consider the 0.9V dropout voltage and 20mA sourcing limit when designing the power stage.

Voltage Reference Part Context

This part belongs to the LT1460 Micropower Precision Series Reference Family. It is available in various packages including SO-8, MSOP-8, PDIP-8, TO-92, and SOT-23. Different letter codes denote varying accuracy and temperature coefficient grades across the family.
