LT3092ETS8#TRMPBF

Current Regulation/Management Overview

The LT3092ETS8#TRMPBF is a programmable two-terminal current source manufactured by Analog Devices Inc. in an 8-pin TSOT-23 surface-mount package. It provides a maximum output current of 200mA, adjustable between 0.5mA and 200mA using only two external resistors. The device operates within a wide supply voltage range of 1.2V to 40V with a typical quiescent current of 300µA. It features high accuracy with a SET pin initial precision of 1% and low temperature coefficient. Line regulation is better than 10ppm/V from 1.5V to 40V. The component functions stably without input or output capacitors, offering high DC and AC impedance suitable for intrinsic safety applications.

Current Regulation/Management Feature Summary

• Programmable two-terminal operation allowing current setting via simple resistor ratios
• Capacitor-free stability ensuring reliable performance in sensitive circuit configurations
• Integrated protection mechanisms including reverse battery, reverse current, current limiting, and thermal shutdown

Current Regulation/Management Applications

• Intrinsic safety barrier circuits
• Sensor driving and excitation
• Remote power supply regulation
• Precision local current limiting

Current Regulation/Management Procurement Notes

Verify the specific suffix TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free compliance status. Confirm availability constraints as distribution channels may indicate limited stock or restricted supply conditions. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability.

Current Regulation/Management Selection Notes

Select this component when a compact, high-impedance current source is required without external stabilization capacitors. It is ideal for applications demanding precise current regulation across a wide voltage span. Consider the TSOT-23-8 package size for space-constrained designs. Evaluate the need for integrated reverse polarity and thermal protection features inherent to this part number.

Current Regulation/Management Part Context

This part belongs to the LT3092 family of programmable current sources. It shares functional characteristics with other variants like the LT3092EDD but differs in physical packaging. The ETS8 designation specifically identifies the 8-pin TSOT-23 form factor. It serves as a fundamental building block for analog signal conditioning and power management tasks requiring stable current delivery.
