LT1460KCS3-3#TRPBF

Voltage Reference Overview

The LT1460KCS3-3#TRPBF is a micropower precision series voltage reference manufactured by Analog Devices Inc. It utilizes curvature compensation and trimmed thin-film resistors to achieve high accuracy with low drift. The device operates within the commercial temperature range of 0°C to 70°C and provides a fixed output voltage of 3V with an initial accuracy of ±0.5%. It features a maximum temperature coefficient of 50ppm/°C, a supply current of 220µA maximum, and can source up to 20mA. The component is housed in a 3-lead SOT-23 package.

Voltage Reference Feature Summary

• Curvature compensated bandgap architecture for low temperature drift
• Capacitive load stability without requiring external output compensation capacitors
• Reverse battery protection 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 the specific ordering suffix #TRPBF confirms tape and reel packaging and lead-free finish status. Confirm the K grade designation matches the required ±0.5% accuracy and 50ppm/°C temperature coefficient specifications. Ensure the C3 suffix corresponds to the 3V output voltage option. Check that the manufacturer is Analog Devices Inc. or its authorized predecessor Linear Technology.

Voltage Reference Selection Notes

Select this part when a fixed 3V reference is needed in a compact SOT-23 form factor. It is suitable for applications where board space is limited due to the elimination of output capacitors. Consider the 50ppm/°C drift specification against system requirements. Verify input voltage remains above VOUT + 0.9V to ensure proper regulation.
