LT1461CCS8-5#PBF

Voltage Reference Overview

The LT1461CCS8-5#PBF is a micropower precision low dropout series voltage reference manufactured by Analog Devices Inc. It provides a fixed 5V output with an initial accuracy of ±0.08% and a maximum temperature coefficient of 12ppm/°C. The device operates within a commercial temperature range of 0°C to +70°C and draws a typical supply current of 35µA. It features a shutdown pin for power management, thermal limiting protection, and supports up to 100mA output current in short-circuit conditions.

Voltage Reference Feature Summary

• Combines high accuracy and low drift with low supply current and high output drive capability
• Utilizes advanced curvature compensation techniques and trimmed precision thin-film resistors
• Includes a shutdown feature to switch full load currents and enable system power down
• Incorporates 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 #PBF indicates lead-free finish and tube packaging when sourcing. Confirm the CCS8 designation corresponds to the C-grade specifications (±0.08% accuracy, 12ppm/°C TC) and commercial temperature range (0°C to 70°C). Ensure the input voltage remains within the specified limits relative to the 5V output to maintain regulation.

Voltage Reference Selection Notes

Select this component for applications requiring a stable 5V reference with moderate precision and low quiescent current. The C-grade offers a balance between cost and performance compared to higher grades. Consider the SOIC-8 package constraints and ensure adequate board layout practices to minimize mechanical stress effects on long-term stability.

Voltage Reference Part Context

This part belongs to the LT1461 family of micropower precision low dropout series voltage references. The family utilizes band-gap technology with curvature compensation. The LT1461CCS8-5#PBF specifically represents the C-grade variant with 5V output, packaged in an 8-lead plastic SOIC format suitable for surface mount assembly.
