LT1461CCS8-2.5#TRPBF

Voltage Reference Overview

The LT1461CCS8-2.5#TRPBF is a micropower precision low dropout series voltage reference from Analog Devices, offering a fixed 2.5V output in an 8-lead plastic SO package with tape and reel packaging. It features an initial accuracy of ±0.08% and a maximum temperature coefficient of 12ppm/°C over the commercial operating range of 0°C to 70°C. The device draws a typical supply current of 35µA and supports up to 50mA output drive current with a maximum dropout voltage of 300mV. It includes a shutdown feature for power management and thermal limiting protection.

Voltage Reference Feature Summary

• Combines high accuracy and low drift with micropower consumption and high output drive capability
• Utilizes advanced curvature compensation and trimmed precision thin-film resistors for stability
• Includes a shutdown pin to switch full load currents and enable system power down
• Features thermal shutdown protection against overload conditions

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'CC' grade corresponds to the required ±0.08% accuracy and 12ppm/°C temperature coefficient specifications. Ensure the commercial temperature range (0°C to 70°C) meets the application requirements. Check for RoHS compliance status as indicated in official documentation.

Voltage Reference Selection Notes

Select this component when a fixed 2.5V reference with micropower operation is required. The CC grade provides a balance of precision and cost for commercial applications. Consider the 50mA drive capability if driving moderate loads directly. Evaluate the need for the shutdown feature for power-sensitive designs. Compare against higher precision grades if tighter tolerance or lower temperature coefficients are necessary.

Voltage Reference Part Context

This part belongs to the LT1461 family of micropower precision low dropout series voltage references. The family offers various output voltages including 2.5V, 3V, 3.3V, 4.096V, and 5V. Different grades (AC, BC, CC, DC) provide varying levels of accuracy and temperature coefficient performance. The S8 package denotes the 8-lead plastic SOIC form factor suitable for surface mount assembly.

Voltage Reference Replacement Considerations

Direct replacements within the same family include LT1461ACS8-2.5#TRPBF for higher precision or LT1461BCS8-2.5#TRPBF for intermediate accuracy. Industrial temperature range variants like LT1461CIS8-2.5#TRPBF are available if wider operating temperatures are needed. Verify pin compatibility and electrical specifications before substitution.
