LT1460JCS3-2.5#TRPBF

Voltage Reference Overview

The LT1460JCS3-2.5#TRPBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in a 3-lead plastic SOT-23 package. It provides a fixed nominal 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. It requires a minimum input-to-output differential voltage of 0.9V and supports a maximum supply current of 175µA.

Voltage Reference Feature Summary

• Curvature compensation combined with trimmed thin-film resistors ensures high output accuracy and low drift across the operating temperature range.
• Capacitive load stability allows for fast settling times without requiring an external output compensation capacitor, saving printed circuit board space.
• Reverse battery protection prevents current conduction during reverse connections, safeguarding the component from damage.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify that the specific ordering suffix matches the required tape and reel packaging configuration. Confirm the temperature grade corresponds to the intended commercial application environment. Ensure the lead-free finish designation aligns with assembly process requirements. Cross-reference the part marking code on the shipping container to validate parametric grades before integration into production designs.

Voltage Reference Selection Notes

Select this component when a compact surface-mount solution is required for precision analog circuits. The SOT-23 package offers a small footprint suitable for space-constrained designs. Consider the 0.9V dropout voltage when designing power rails to ensure sufficient headroom. Evaluate the 175µA supply current against total system power budgets for portable applications.
