LT1461BCS8-5#TRPBF

Voltage Reference Overview

The LT1461BCS8-5#TRPBF is a micropower precision low dropout series voltage reference from Analog Devices, packaged in an 8-lead plastic SOIC (SO-8) tape and reel. It provides a fixed 5V output with an initial accuracy of ±0.06% and a maximum temperature coefficient of 7ppm/°C over the commercial operating range of 0°C to 70°C. The device draws a typical supply current of 35µA and supports a minimum output drive current of 50mA. It features a shutdown pin for power management and includes thermal limiting protection.

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 limiting to protect the part from overload conditions

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific ordering suffix #TRPBF confirms the tape and reel packaging format required for automated assembly processes. Ensure the B grade designation matches the required ±0.06% initial accuracy and 7ppm/°C temperature coefficient specifications for your design. Confirm the commercial temperature range of 0°C to 70°C aligns with your environmental constraints before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a fixed 5V reference with micropower consumption is needed alongside moderate load drive capabilities. The B grade offers a balance between cost and performance, suitable for general-purpose precision applications. Consider the SO-8 package size and tape and reel availability if space constraints or high-volume surface mount assembly are primary design drivers.

Voltage Reference Part Context

This part belongs to the LT1461 family of micropower precision low dropout series voltage references. The family utilizes bandgap technology to achieve high accuracy and low drift. The LT1461BCS8-5#TRPBF specifically denotes the B grade accuracy, 5V output version, packaged in an 8-lead SOIC format supplied in a tape and reel configuration for manufacturing efficiency.
