Overview
The LM1086CSX-3.3/J7001710 is a fixed positive low-dropout linear voltage regulator manufactured by Texas Instruments. It provides a fixed output voltage of 3.3 V with a maximum load current capability of 1.5 A. The device operates within an input voltage range up to 29 V and features a typical dropout voltage of 1.3 V at full load. It is housed in a TO-263 (D2PAK-3) surface-mount package, suitable for applications requiring efficient power regulation in compact designs.
Feature Summary
- Fixed 3.3 V output voltage configuration
- High current delivery capability up to 1.5 A
- Low dropout voltage operation for efficiency
- Surface-mount TO-263 package integration
Applications
- Point-of-load regulation in embedded systems
- Battery-powered equipment power conditioning
- General-purpose positive voltage regulation circuits
Procurement Notes
Verify the exact suffix J7001710 against official Texas Instruments documentation to confirm it denotes a specific tape-and-reel quantity or packaging variant rather than a functional change. Ensure compatibility with standard TO-263 footprints during procurement planning.
Selection Notes
Select this component when a stable 3.3 V rail is required for loads drawing up to 1.5 A. The TO-263 package offers thermal performance advantages over smaller SOT packages. Verify that the input voltage does not exceed the 29 V absolute maximum rating under all operating conditions.
Part Context
This part belongs to the LM1086 family of 1.5-A low-dropout positive voltage regulators. It shares pin-out compatibility with industry-standard devices like the LM317 but offers fixed voltage options. The series is designed for applications requiring simple regulation with minimal external components.
Replacement Considerations
Consult official substitution guides for equivalents such as the LM1086CSX-3.3/NOPB. Verify that any substitute maintains the same TO-263 footprint and 1.5 A current rating.
