LT3092EST#TRPBF

Current Regulation/Management Overview

The LT3092EST#TRPBF is a programmable two-terminal current source manufactured by Analog Devices Inc. in an SOT-223-3 package. It supports an output current range of 0.5mA to 200mA, set via external resistors. The device operates within a supply voltage range of 1.2V to 40V and maintains stability without input or output capacitors. It features a SET pin with ±1% initial accuracy and low temperature coefficient. Current regulation is better than 10ppm/V between 1.5V and 40V. The component functions as a high impedance source suitable for intrinsically safe applications.

Current Regulation/Management Feature Summary

• Two-terminal programmable current source configuration
• Capacitor-free stability for high DC and AC impedance
• Integrated reverse battery and reverse current protection
• Current limiting and thermal shutdown safeguards

Current Regulation/Management Applications

• Intrinsically safe circuit design
• Remote power supply regulation
• Precision local current limiting
• Sensor driving applications

Current Regulation/Management Procurement Notes

Verify the specific suffix #TRPBF confirms tape and reel packaging when sourcing. Confirm the EST designation corresponds to the SOT-223-3 package variant rather than other available packages like TSOT-23-8 or DFN. Ensure the manufacturer is identified as Analog Devices Inc. to guarantee component authenticity and datasheet alignment.

Current Regulation/Management Selection Notes

Select this model for applications requiring a simple two-wire current source solution without external compensation components. The SOT-223-3 package offers a compact footprint suitable for surface mount assembly. Consider the 200mA maximum output capability and 40V voltage rating to ensure adequate headroom for the target load requirements.

Current Regulation/Management Part Context

This component belongs to the LT3092 family of programmable current sources from Analog Devices. The family includes variants such as LT3092ETS8 and LT3092EST, differing primarily in package type. The EST variant specifically utilizes the SOT-223-3 housing, providing a distinct physical form factor compared to the TSOT-23-8 or DFN options available in the same product line.
