Overview
The LD1086V50 is a positive low-dropout voltage regulator from the STMicroelectronics LD1086 series. It provides a fixed output voltage of 5 V with a maximum output current capability of 1.5 A. The device operates within an input voltage range of 3.4 V to 30 V and features a typical dropout voltage of 1.3 V at full load. It includes internal thermal overload protection and short-circuit current limiting. The component is designed for through-hole mounting in TO-220-3 packages and supports operation across a temperature range of -40 °C to +125 °C.
Feature Summary
- Fixed 5 V output voltage regulation
- High current delivery up to 1.5 A
- Integrated thermal and short-circuit protection
Applications
- General-purpose power supply circuits requiring stable 5 V rails
- Battery-powered systems needing efficient voltage regulation
- Industrial control equipment power distribution
Procurement Notes
Verify the specific package variant, such as TO-220-3, against design requirements. Confirm RoHS compliance status via official documentation. Ensure input voltage remains within the specified 3.4 V to 30 V range during operation. Check for available lead-free options if required by manufacturing standards.
Selection Notes
Select this component when a fixed 5 V output is required with high current capacity. Consider the TO-220-3 package for through-hole assembly needs. Evaluate thermal management requirements due to the 1.5 A output capability. Compare against adjustable variants if flexible voltage settings are needed instead.
Part Context
This part belongs to the LD1086 family of positive low-dropout regulators. The series offers both adjustable and fixed output versions. The LD1086V50 specifically targets applications requiring a stable 5 V supply. It shares common protection features like thermal shutdown with other members of the family.
