LD1086D2T33TR
Overview
The LD1086D2T33TR is a fixed 3.3V linear voltage regulator capable of providing up to 1.5A of output current. It is designed to handle an input voltage up to 30V and features internal current and thermal limiting to protect the device and downstream circuitry. This regulator is housed in a D2PAK surface-mount package, offering a balance of high current capability and thermal dissipation for PCB-based power management.
Why Choose This Part
This regulator offers high ripple rejection of 79dB at 120Hz, making it effective at cleaning up power rails. It supports a wide operating temperature range of -40 to 125 degrees Celsius and includes robust protection features like over-current and over-temperature shutdown. The 1.5A output rating provides significant headroom compared to standard 1A regulators in the same footprint.
Applications
Key Specifications
Getting Started
When designing with the LD1086D2T33TR, ensure a minimum of 10uF tantalum or electrolytic capacitor is placed on the output for stability. The D2PAK tab is electrically connected to the output pin, so thermal layout should include sufficient copper area to manage heat dissipation at high current loads. Verify that the input voltage remains at least 1.5V above the 3.3V output to maintain proper regulation across all load conditions.
