LT1460HCS3-2.5#TRMPBF

Voltage Reference Overview

The LT1460HCS3-2.5#TRMPBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in a 3-lead 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 up to 175µA, a minimum input-to-output differential voltage of 0.9V, and a maximum input voltage of 20V. It supports a sourcing load current of up to 40mA.

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 eliminates the need for external output compensation capacitors, facilitating fast settling times and compact board layouts.
• 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

Voltage Reference Procurement Notes

Verify the specific suffix TRMPBF indicates tape and reel packaging containing 500 pieces as documented in the ordering information. Confirm the H grade corresponds to the 0.2% accuracy and 20ppm/°C temperature coefficient specifications. Ensure the lead-free finish matches RoHS3 compliance requirements. Cross-reference the manufacturer part number with distributor listings to confirm active status and availability.

Voltage Reference Selection Notes

Select this component when a small SOT-23 footprint is required alongside micropower consumption. The 2.5V output suits applications needing stable references for ADCs or DACs. Verify that the 0.9V dropout voltage meets the system's minimum input voltage constraints. Consider the 40mA sourcing capability if higher drive currents are necessary compared to standard shunt references.

Voltage Reference Part Context

This part belongs to the LT1460 Micropower Precision Series Reference Family. The family offers various packages including SO-8, MSOP-8, PDIP-8, TO-92, and SOT-23. Different grades (A through K) provide varying levels of accuracy and temperature coefficients. The H grade specifically targets the 0.2% accuracy tier in the compact SOT-23 form factor.
