LT3092IST#PBF

Current Regulation/Management Overview

The LT3092IST#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 a SET pin with 1% initial accuracy and low temperature coefficient. Operating supply current is 300µA, with a minimum operating temperature of -40°C and a maximum of +125°C. It utilizes low-side sensing and is housed in a surface-mount SOT-223-3 package.

Current Regulation/Management Feature Summary

• Programmable two-terminal configuration requiring only two resistors for current setting
• High stability without input or output capacitors, offering high DC and AC impedance
• Integrated protection circuits including reverse battery, reverse current, limit, and thermal shutdown

Current Regulation/Management Applications

• Two-terminal floating current sources
• Ground-referenced current sources
• In-line current limiters
• Intrinsically safe circuit designs

Current Regulation/Management Procurement Notes

Verify the specific suffix #PBF indicates tube packaging versus TRPBF for tape-and-reel. Confirm the IST variant corresponds to the SOT-223-3 package type. Check current availability status as distribution may vary. Ensure compatibility with low-side sensing requirements in the target circuit design before procurement.

Current Regulation/Management Selection Notes

Select this component when a compact, capacitor-free current source is required for precision applications. The SOT-223-3 package suits space-constrained designs needing robust thermal performance. Consider the 1.2V to 40V input range and 200mA max output when sizing for sensor driving or local power limiting tasks.

Current Regulation/Management Part Context

The LT3092 series includes variants such as LT3092IDD and LT3092ETS8, differing primarily in package types like DFN-8 and TSOT-23-8. The IST#PBF specifically denotes the SOT-223-3 surface-mount option. All variants share core electrical characteristics, enabling flexible layout choices while maintaining identical functional performance across the family.

Current Regulation/Management Replacement Considerations

LT3092ETS8#TRMPBF is a confirmed substitute with similar functionality and TSOT-23-8 packaging.
