LT1461DHS8-5#TRPBF

Voltage Reference Overview

The LT1461DHS8-5#TRPBF is a micropower precision low dropout series voltage reference from Analog Devices, packaged in an 8-lead plastic SOIC. It provides a fixed 5V output with an initial accuracy of ±0.15% and a maximum temperature coefficient of 20ppm/°C over the –40°C to 125°C range. The device draws 35µA typical supply current and supports up to 100mA output drive current. It features a shutdown pin for power management and operates with an input voltage range of 5.5V to 20V.

Voltage Reference Feature Summary

• Advanced curvature compensation techniques ensure low temperature drift and high output accuracy.
• Integrated shutdown capability allows switching full load currents and enables system power down modes.
• Thermal shutdown protection safeguards the component 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 this part number. Confirm the DH grade corresponds to the required –40°C to 125°C operating temperature range and ±0.15% accuracy specifications. Ensure compatibility with 8-lead SOIC surface mount assembly processes during procurement planning.

Voltage Reference Selection Notes

Select this variant for applications requiring wide industrial temperature operation and moderate precision. The 5V output option suits systems needing standard logic levels or reference voltages. Consider the 35µA quiescent current for battery-powered designs where efficiency is critical alongside drive capability.

Voltage Reference Part Context

This component belongs to the LT1461 family of bandgap references designed for low power and portable applications. The family combines high accuracy with low supply current and high output drive capabilities. The DH sub-series specifically targets extended temperature environments while maintaining stable performance characteristics.
