LT3092ETS8#TRPBF

Current Regulation/Management Overview

The LT3092ETS8#TRPBF is a programmable two-terminal current source manufactured by Analog Devices Inc. It operates within an input voltage range of 1.2V to 40V and delivers a maximum output current of 200mA. The device maintains high stability without requiring external input or output capacitors, offering high DC and AC impedance suitable for intrinsic safety applications. It features a SET pin with 1% initial accuracy and low temperature coefficient. Current regulation is better than 10ppm/V across the 1.5V to 40V range. The component functions in surface-mount TSOT-23-8 packaging and supports operation temperatures from -40°C to +125°C.

Current Regulation/Management Feature Summary

• Programmable two-terminal configuration allowing dynamic current setting via resistor ratios

• Integrated protection mechanisms including reverse battery, reverse current, current limiting, and thermal shutdown

Current Regulation/Management Applications

• Two-terminal floating current sources
• Ground-referenced current sources
• Intrinsically safe circuit designs
• Precision local power supply current limiters

Current Regulation/Management Procurement Notes

Verify the specific suffix TRPBF confirms tape and reel packaging when sourcing. Confirm the ETS8 designation matches the required TSOT-23-8 package variant. Ensure the order specifies the correct temperature grade for the intended operating environment. Cross-reference the manufacturer part number against official Analog Devices documentation to avoid counterfeit components. Validate RoHS compliance status through the official datasheet before final procurement.

Current Regulation/Management Selection Notes

Select this component when a stable, capacitor-free current source is required for sensitive analog circuits. The wide input voltage range accommodates various supply rails up to 40V. High impedance characteristics make it ideal for applications where minimal loading on the signal line is critical. Consider the TSOT-23-8 package constraints for PCB layout space. Evaluate the 1% SET pin accuracy against system tolerance requirements.

Current Regulation/Management Part Context

This device belongs to the LT3092 series of adjustable current sources from Analog Devices. It shares functional similarities with other two-terminal regulators but distinguishes itself through its lack of external capacitance requirements. The series includes variants like the LT3092EDD in DFN packages. It serves as a fundamental building block for precision current generation in industrial and instrumentation systems.

Current Regulation/Management Replacement Considerations

LT3092ETS8#TRMPBF offers identical electrical specifications and functionality but utilizes cut-tape packaging instead of tape-and-reel. Verify that the change in packaging format aligns with automated assembly equipment capabilities. No other direct substitutes are confirmed in the provided documentation.
