LT1461BCS8-3#TRPBF

Voltage Reference Overview

The LT1461BCS8-3#TRPBF is a micropower precision low dropout series voltage reference manufactured by Analog Devices Inc. It provides a fixed 3V output with an initial accuracy of ±0.06% and a maximum temperature coefficient of 7ppm/°C. The device operates within a supply voltage range of (VOUT + 0.5V) to 20V, drawing a typical supply current of 35µA. It features a minimum output drive capability of 50mA and includes a shutdown pin for power management. The component is housed in an 8-lead plastic SO package and is specified for operation from 0°C to 70°C.

Voltage Reference Feature Summary

• Advanced curvature compensation techniques combined with trimmed precision thin-film resistors ensure high output accuracy and low drift.
• Integrated shutdown feature allows switching full load currents and enables system power down modes.
• Built-in thermal shutdown protection safeguards the part against overload conditions.

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the B-grade designation corresponds to the required ±0.06% accuracy and 7ppm/°C temperature coefficient specifications for your design. Ensure the commercial temperature range of 0°C to 70°C meets your operational environment requirements before finalizing procurement.

Voltage Reference Selection Notes

Select this component when a fixed 3V reference with high precision is required alongside low quiescent current consumption. The 50mA output drive capability makes it suitable for driving moderate loads directly or serving as a reference for precision regulators. Consider the 8-lead SO package constraints and the necessity of input and output capacitors for stability during circuit design.

Voltage Reference Part Context

This part belongs to the LT1461 family of micropower precision low dropout series voltage references. The 'B' grade denotes a tighter initial accuracy specification compared to standard grades, while the 'CS8' indicates the 8-lead SOIC package variant. The '#TRPBF' suffix specifies lead-free tape and reel packaging for automated assembly processes.

Voltage Reference Replacement Considerations

LT1461BCS8-3#PBF is a confirmed direct substitute offering identical electrical characteristics but packaged in tubes instead of tape and reel.
