LD1117S50TR
Overview
The LD1117S50TR is a low dropout linear regulator (LDO) providing a fixed 5V output at up to 800mA. It is designed to offer stable power regulation with internal current and thermal limiting protection, making it a robust choice for point-of-load regulation. The device features a high power supply rejection ratio (PSRR) of 75dB at 120Hz to minimize noise from upstream supplies.
Why Choose This Part
The LD1117S50TR offers a high output current capability of 800mA in a compact SOT-223 package, providing significantly more headroom than standard 150mA regulators. It maintains tight output voltage accuracy within 1 percent at room temperature and 2 percent across the full 0 to 125 degrees Celsius operating range.
Applications
Key Specifications
Getting Started
To use this regulator, ensure an input voltage of at least 6.5V is provided to meet the dropout requirements. Always place a 10uF or larger capacitor on the output and a 100nF capacitor on the input close to the device pins to ensure stability and transient response. No external programming resistors are needed for this fixed 5V version.
