LT1461BCS8-2.5#TRPBF

Voltage Reference Overview

The LT1461BCS8-2.5#TRPBF is a micropower precision low dropout series voltage reference from Analog Devices Inc., housed in an 8-lead plastic SO package. It provides a fixed 2.5V output with a maximum 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 operates within an input voltage range of VOUT + 0.5V to 20V, featuring a maximum dropout voltage of 300mV at 50mA load.

Voltage Reference Feature Summary

• Combines high accuracy and low drift with micropower consumption and high output drive capability
• Utilizes advanced curvature compensation techniques for low temperature coefficient performance
• Incorporates a shutdown feature to switch full load currents and enable system power down
• Includes thermal limiting protection to prevent damage during 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 B grade designation corresponds to the required ±0.06% accuracy and 7ppm/°C temperature coefficient specifications. Ensure the commercial temperature range (0°C to 70°C) aligns with the application environment requirements before finalizing procurement.

Voltage Reference Selection Notes

Select this component for applications requiring a stable 2.5V reference with minimal quiescent current draw. The 50mA output drive capability allows it to function as a precision regulator or drive moderate loads directly. Consider the 8-lead SO package constraints and ensure adequate board space for recommended bypass capacitors to maintain stability under varying load conditions.
