LT3092EST#PBF

Current Regulation/Management Overview

The LT3092EST#PBF is a programmable two-terminal current source manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.2V to 40V and delivers an output current between 0.5mA and 200mA. The device features 1% initial accuracy for the SET pin current and maintains a typical linear regulation better than 10ppm/V across the operating range. It functions without input or output capacitors, ensuring stability in high-impedance environments. The component supports surface mount installation in a SOT-223-3 package and operates reliably from -40°C to +125°C.

Current Regulation/Management Feature Summary

• Programmable two-terminal current source configuration requiring only two external resistors
• Capacitor-free operation with high DC and AC impedance suitable for sensitive applications
• Integrated protection mechanisms including reverse battery, reverse current, limit, and thermal shutdown

Current Regulation/Management Applications

• Intrinsically safe circuits
• Remote power supplies
• Precision local current limiters

Current Regulation/Management Procurement Notes

Verify the specific suffix #PBF indicates tape-and-reel packaging when ordering. Confirm the SOT-223-3 package variant matches the design requirements. Ensure compatibility with the 1.2V to 40V input voltage range. Check for availability constraints as distribution status may vary. Validate that the 200mA maximum output current meets the load specifications.

Current Regulation/Management Selection Notes

Select this component for applications requiring precise current regulation without complex control loops. The wide input voltage range allows flexibility in power supply design. The absence of required output capacitors simplifies layout and improves transient response. Consider the thermal performance within the specified temperature range for robust operation in demanding environments.

Current Regulation/Management Part Context

This part belongs to the LT3092 series of programmable current sources. It shares core functionality with variants like LT3092IDD and LT3092ETS8 but differs in package type. The EST designation specifically identifies the SOT-223-3 surface mount package. This family is designed for simple, reliable current sourcing in industrial and instrumentation systems.

Current Regulation/Management Replacement Considerations

LT3092ETS8#TRPBF offers identical electrical characteristics in a TSOT-23-8 package. LT3092IDD#PBF provides the same performance in a DFN-8 package. Verify pinout compatibility and thermal dissipation capabilities when substituting packages.
