High-Current 3.3V Linear Voltage Regulator 800mA for Microcontrollers, Embedded Systems, and Industrial Power Circuits – SOIC-8 Package

The LD1117D33TR is a fixed-output linear voltage regulator designed to provide a stable and regulated 3.3V supply for a wide range of electronic circuits. Capable of delivering up to 800mA output current, this regulator is suitable for powering microcontrollers, development boards, communication modules, and other digital or analog devices that require reliable 3.3V power. The device is based on the widely used 1117 regulator architecture, known for its dependable voltage regulation and consistent performance.

Encased in a compact SOIC-8 surface-mount package, the LD1117D33TR enables efficient PCB integration in embedded systems, industrial electronics, and consumer devices. Its low dropout design allows efficient operation when the input voltage is only slightly higher than the output voltage. The regulator offers good line and load regulation, ensuring stable output even when the input supply fluctuates or the load changes. Integrated protection features such as current limiting and thermal shutdown enhance reliability and safeguard connected circuits.
