LD1086DT50TR
Overview
The LD1086DT50TR is a low dropout positive voltage regulator capable of providing up to 1.5A of output current with a fixed 5V output. It features a high Power Supply Rejection Ratio (PSRR) of 75dB at 120Hz and operates with an input voltage up to 30V. This device is designed to maintain high efficiency in power management circuits while offering integrated protection against over-current and over-temperature conditions.
Why Choose This Part
The LD1086DT50TR offers tight output accuracy of 1 percent and is pin-compatible with standard linear regulators, making it an easy drop-in upgrade. It includes internal power and thermal limiting to protect the device and downstream loads from damage. The high PSRR makes it particularly effective at minimizing ripple in sensitive analog or digital applications.
Applications
Key Specifications
Getting Started
When designing with the LD1086DT50TR, ensure a minimum 10uF tantalum capacitor is placed on the output for stability as per datasheet recommendations. For prototyping, the DPAK package can be mounted on a breakout board, but adequate copper pour area is required on the PCB for heat dissipation at high current loads. Verify the input-to-output voltage differential stays within the dropout limits to maintain regulation.
