LT1460JCS3-2.5#TRMPBF

Voltage Reference Overview

The LT1460JCS3-2.5#TRMPBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in a 3-lead plastic SOT-23 package. It delivers a fixed output voltage of 2.5V with an initial accuracy tolerance of ±0.4%. The device operates within a commercial temperature range of 0°C to 70°C and features a maximum temperature coefficient of 20ppm/°C. Electrical specifications include a maximum supply current of 175µA, a minimum input-to-output differential voltage of 0.9V, and the capability to source up to 20mA of load current.

Voltage Reference Feature Summary

• Utilizes curvature compensation and trimmed thin-film resistors for high accuracy and low drift
• Operates without requiring an external output compensation capacitor while maintaining stability with capacitive loads
• Provides reverse battery protection by preventing current conduction during reverse connections

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify that the ordering suffix #TRMPBF corresponds to the Tape and Reel Mini packaging format containing 500 pieces. Confirm the specific temperature grade 'J' indicates the 0°C to 70°C commercial range. Ensure the component matches the 3-lead SOT-23 physical footprint required for the design. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity and lead-free finish status.

Voltage Reference Selection Notes

Select this component when a compact SOT-23 form factor is required alongside moderate precision levels. The J-grade offers a balance between cost and performance for commercial applications. Consider the 20ppm/°C temperature coefficient and 0.4% initial accuracy against stricter requirements found in higher grades like A or B. Evaluate the 175µA supply current consumption relative to battery life constraints in portable designs.
