STMicroelectronics Voltage Regulators - Linear LD1117S50CTR

The LD1117S50CTR is a linear voltage regulator from Quarktwin Technology Ltd. designed to provide a fixed output voltage of 5.0 V with a maximum output current of 800 mA. It features a low dropout voltage of approximately 1 V, making it suitable for applications requiring efficient voltage regulation. The device is available in multiple package types, including SOT-223, DPAK, SO-8, and TO-220, which allows for flexibility in design and layout. The regulator offers a supply voltage rejection ratio of 75 dB (typical), ensuring stable output under varying input conditions. It also includes internal current and thermal limiting for enhanced reliability. The LD1117S50CTR is characterized by a tight output voltage tolerance of ¬± 1% at 25 ¬8C, making it a reliable choice for precision applications.
