Overview
Description
The LD1117DT50CTR is a low-dropout (LDO) voltage regulator from STMicroelectronics. It is designed to provide a stable output voltage of 5V with a maximum output current of 800mA. The "LD1117" series is known for its efficiency in converting higher input voltages to lower output voltages with minimal power loss, thanks to its low dropout voltage of around 1.2V at the maximum output current.
The "DT" in the part number indicates the device's package type, which is typically DPAK, a surface-mount package commonly used for power devices. "50" specifies the fixed output voltage of 5.0V, and "CTR" usually refers to the tape and reel packaging, which is suitable for automated assembly processes.
The LD1117DT50CTR is ideal for applications in consumer electronics, computer peripherals, and other devices where space and power efficiency are crucial. It features protections like thermal shutdown and current limiting, ensuring reliability under varying operational conditions. This regulator is valued for its ease of use and robust performance in low to medium power applications.
