Overview
The LF85CDT-TRY is a fixed-output linear voltage regulator from the STMicroelectronics LF series, housed in a DPAK surface-mount package. It provides a fixed positive output of 8.5 V with a maximum continuous output current of 500 mA. The device operates within an input voltage range of 9.5 V to 16 V and features a typical dropout voltage of 0.7 V at full load. It includes internal protection against overcurrent and thermal overload, ensuring reliability across an operating temperature range of -40°C to +125°C.
Feature Summary
- Integrated overcurrent and thermal shutdown protection mechanisms for enhanced circuit safety
- AEC-Q100 qualified for automotive application reliability standards
- Fixed 8.5 V output configuration suitable for stable power supply requirements
Applications
- Automotive electronic systems requiring AEC-Q100 compliant components
- General purpose linear voltage regulation in industrial equipment
- Power management circuits in consumer electronics
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance and REACH SVHC declarations prior to integration. Ensure packaging specifications match design requirements, as availability may vary between reel, cut tape, or MouseReel formats depending on supplier inventory.
Selection Notes
Select this component when a fixed 8.5 V output is required with up to 500 mA load capability. Consider the DPAK package for surface-mount assembly constraints. Evaluate thermal performance based on the specified junction temperature range and ensure input voltage remains within the 9.5 V to 16 V operational window for proper regulation.
Part Context
This part belongs to the LFxx series of low-dropout regulators manufactured by STMicroelectronics. It is categorized under PMIC - Power Management ICs, specifically Linear Voltage Regulators. The device utilizes planar technology for robust performance in various environmental conditions.
Replacement Considerations
The LF85CDT-TR is a verified substitute part number offering identical electrical characteristics and pinout compatibility. Verify package integrity and marking consistency when transitioning between these variants.
