LT1461BCS8-5#PBF

Voltage Reference Overview

The LT1461BCS8-5#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 ±0.06% and a maximum temperature coefficient of 3ppm/°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, thermal limiting protection, and operates within an input voltage range up to 20V.

Voltage Reference Feature Summary

• Combines high accuracy and low drift with micropower consumption and high output drive capability
• Includes a dedicated shutdown pin to switch full load currents and enable system power down
• Features internal thermal limiting to protect 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 tube packaging when reviewing distributor listings. Confirm the B grade designation corresponds to the required ±0.06% accuracy and 3ppm/°C temperature coefficient specifications. Ensure the SOIC-8 package matches the PCB footprint requirements. Check for RoHS compliance status in the latest datasheet revision.

Voltage Reference Selection Notes

Select this component when a fixed 5V reference with high precision is needed alongside moderate load driving capabilities. The low dropout characteristic ensures efficiency in battery-powered systems. Consider the shutdown feature if system power management requires active control of the reference output. Verify that the commercial temperature range meets the application environment constraints.
