LT1460HCS3-2.5#TRPBF

Voltage Reference Overview

The LT1460HCS3-2.5#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 output voltage of 2.5V with an initial accuracy tolerance of ±0.2%. 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 supply current of 175µA, a minimum input voltage differential of 0.9V, and a maximum input voltage of 20V. It supports up to 40mA output current and exhibits low noise characteristics.

Voltage Reference Feature Summary

• Combines curvature compensation with trimmed precision thin-film resistors for high accuracy and low drift
• Operates as a series reference without requiring an output compensation capacitor while remaining stable with capacitive loads
• Includes reverse battery protection that prevents 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 #TRMPBF against official documentation to confirm tape and reel packaging details. Ensure the component matches the designated commercial temperature grade (0°C to 70°C) required for the application environment. Cross-reference the manufacturer part number with authorized distributor lists to validate authenticity and traceability before procurement.

Voltage Reference Selection Notes

Select this component when a compact surface-mount solution is required for precision voltage referencing. The SOT-23 package offers space efficiency compared to larger 8-lead options. Consider the 20ppm/°C temperature coefficient and ±0.2% initial accuracy for applications demanding stability within the commercial temperature range. Verify that the 175µA supply current meets power budget constraints.

Voltage Reference Part Context

This part belongs to the LT1460 Micropower Precision Series Reference Family. The family utilizes bandgap technology to achieve high accuracy and low drift. Variants are available in multiple packages including MSOP, SO, PDIP, TO-92, and SOT-23, with different temperature grades and accuracy levels to suit various industrial and commercial needs.
