LDL1117S18R Description

Short technical summary and product information.

The STMicroelectronics LDL1117S18R is a linear voltage regulator IC designed for power management applications. It provides a fixed 18V output voltage and can handle a current of 500 µA. The device features a low voltage dropout of 0.6V at 1.2A and offers protection against over current, over temperature, and under voltage lockout (UVLO).

 

This regulator operates within a temperature range of -40°C to 125°C (TJ). It is housed in a SOT-223 package, also compatible with TO-261-4 and TO-261AA formats, and is designed for surface mounting.

 

The LDL1117S18R is suitable for various electronic designs requiring a stable and regulated voltage supply. Its PSRR rating of 87dB to 65dB across a frequency range of 120Hz to 100kHz indicates good noise suppression capabilities.
