Overview
The LD1086V80 is a positive fixed linear voltage regulator from the STMicroelectronics LD1086 series. It provides a fixed output voltage of 8.0 V with a maximum output current capability of 1.5 A. The device features a low dropout voltage, guaranteed at a maximum of 1.2 V under full load conditions. It operates within an input voltage range up to 30 V and supports junction temperatures up to +125 °C. The component is housed in a TO-220 package.
Feature Summary
- Capable of delivering up to 1.5 A of continuous output current
- Low dropout voltage performance ensuring efficient regulation
- Integrated thermal protection mechanisms for operational safety
Applications
- General purpose power supply circuits requiring stable 8 V rails
- Battery-powered systems utilizing linear regulation
- Embedded electronics requiring fixed positive voltage sources
Procurement Notes
Verify the specific package variant and suffix codes against official STMicroelectronics documentation to ensure compatibility with your design requirements. Confirm that the procurement channel provides genuine components with traceable manufacturing data. Cross-reference the part number with the latest datasheet revisions to validate electrical specifications and compliance standards before finalizing orders.
Selection Notes
Select this component when a fixed 8.0 V output is required with high current capacity up to 1.5 A. Ensure the input voltage does not exceed the 30 V absolute maximum rating. Consider the thermal dissipation capabilities of the TO-220 package relative to the expected load current and ambient temperature conditions to maintain safe operating junction temperatures.
Part Context
This part belongs to the LD1086 family of low-dropout regulators manufactured by STMicroelectronics. The series offers various fixed output voltages and current ratings. The LD1086V80 specifically denotes the 8.0 V output variant packaged in TO-220, distinguishing it from surface-mount or different voltage options within the same product line.
Replacement Considerations
Compatible substitutes include other LD1086 variants with identical pinouts and similar electrical characteristics, provided the output voltage matches the system requirement. Verify thermal resistance and package dimensions when swapping between manufacturers.
