ONNCP1117ST33T3G
Overview
The NCP1117ST33T3G is a low dropout positive fixed voltage regulator capable of providing over 1.0A of output current. It is designed to provide a stable 3.3V rail from input voltages up to 20V, making it a reliable choice for point-of-load regulation in various electronic systems. This regulator includes internal current limiting and thermal shutdown protection to ensure robust operation under fault conditions.
Why Choose This Part
This regulator offers an output voltage trimmed to +/- 1.0 percent accuracy and requires no minimum load to maintain regulation. It features a high Power Supply Rejection Ratio (PSRR) of 64dB at 120Hz, which is effective at filtering out input noise. The SOT-223 package provides a balance of small footprint and sufficient thermal performance for 1A loads.
Applications
Key Specifications
Getting Started
When designing with this part, ensure that a minimum of 10uF tantalum or electrolytic capacitance is placed at the output for stability. For prototyping, the SOT-223 package can be adapted to breadboards using standard breakout boards, though care should be taken with thermal dissipation at high current levels. Consult the datasheet to calculate the required copper area on the PCB for heat sinking based on your expected power dissipation.
