Overview
The LM1085I-ADJ MDC is a die version of the LM1085 series, a 3-A low dropout positive regulator manufactured by Texas Instruments. It features an adjustable output voltage range and supports input voltages up to 29 V. The component includes internal current limiting and thermal protection circuits to ensure safe operation under overload conditions. Designed for surface-mount integration, it serves as a high-current linear regulator solution for power management applications requiring precise voltage regulation within its specified operating temperature range.
Feature Summary
- Provides adjustable positive output voltage regulation with a maximum load current capacity of 3 A
- Integrates internal current limiting and thermal shutdown protection mechanisms
- Offers low dropout performance suitable for efficient linear regulation
Applications
- Power supply modules requiring adjustable voltage rails
- Battery-powered systems needing efficient linear regulation
- Embedded electronics utilizing die-level integration
Procurement Notes
Verify that the procurement source provides genuine Texas Instruments LM1085I-ADJ MDC dies. Confirm the specific lot code and manufacturing date against official documentation. Ensure proper handling procedures are followed due to the exposed die format. Validate compliance with relevant environmental standards if required for the final assembly process.
Selection Notes
Select this component when a 3-A adjustable linear regulator is needed in a die form factor for custom packaging or board-level integration. Consider the thermal dissipation requirements associated with the TO-220 family electrical characteristics despite the die package. Ensure the application voltage does not exceed the 29-V maximum input rating.
Part Context
This part belongs to the LM1085 family of low dropout regulators from Texas Instruments. It shares electrical specifications with the packaged LM1085IS-ADJ/NOPB but is supplied as a bare die. The family is known for providing stable regulation with minimal external components, serving as a robust alternative to standard three-terminal adjustable regulators like the LM317.
Replacement Considerations
The LM1085IS-ADJ/NOPB is a packaged equivalent offering identical electrical performance in a TO-263 package. For direct die replacement, verify compatibility with existing substrate materials and bonding processes.
