LD1086VY

Overview

The LD1086VY is a positive adjustable linear voltage regulator from STMicroelectronics, capable of delivering up to 1.5 A output current. It operates with a maximum input voltage of 30 V and features a low dropout characteristic, guaranteed at a maximum of 1.2 V under full load conditions. The device is housed in a TO-220 package with three pins, designed for surface or through-hole mounting depending on the specific variant configuration within the series. It supports an operating temperature range extending up to 125 °C, ensuring reliability in demanding environments.

Feature Summary

• Capable of providing high output current up to 1.5 A for power-intensive applications
• Features low dropout voltage performance to maintain regulation with minimal input-output differential
• Designed for direct connection to automotive battery systems due to robust input voltage tolerance

Applications

• Standby microprocessor control-unit systems
• Automotive electronic applications requiring direct battery connection
• General purpose positive voltage regulation circuits

Procurement Notes

Verify the exact suffix against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Ensure the selected component matches the required adjustable voltage range and package type specifications for your PCB layout. Cross-reference the part number with authorized distributors to confirm authenticity and availability status before finalizing procurement decisions.

Selection Notes

Select this component when a stable 1.5 A supply is needed with adjustable output flexibility. Consider the thermal dissipation requirements of the TO-220 package for high-current loads. Verify that the input voltage does not exceed the 30 V maximum rating. Ensure compatibility with the target application's ground reference and heat sinking capabilities for optimal performance.

Part Context

This component belongs to the LD1086 family of low-dropout regulators manufactured by STMicroelectronics. The family includes both fixed and adjustable variants, such as the LD1085 series which offers higher current capabilities. The LD1086VY specifically denotes the adjustable version in a TO-220 package, distinguishing it from surface-mount options like the DT50TR variant.

Replacement Considerations

Check for LD1086VX or other suffixes in the same series for identical electrical characteristics but different packaging or temperature grades. Consult the official datasheet for pin-compatible alternatives within the LD1085 or LD1084 families if current requirements differ.
