LDL1117S12R Description

Short technical summary and product information.

The STMicroelectronics LDL1117S12R is a linear voltage regulator belonging to the Voltage Regulators - Linear category. It provides a fixed positive output voltage of 1.185V, with a nominal output current of 500 µA, and a higher current capability of 1.2A mentioned in the product description. The device operates within a temperature range of -40°C to 125°C (TJ) and features protection mechanisms including over current, over temperature, and under voltage lockout (UVLO).

 

This regulator is housed in a SOT-223 surface mount package, also referred to as TO-261-4 or TO-261AA. It offers a voltage dropout of 0.6V at 1.2A and has a Power Supply Rejection Ratio (PSRR) ranging from 87dB to 65dB across a frequency range of 120Hz to 100kHz. The maximum input voltage is rated at 18V.

 

Compliance information indicates RoHS3 compliance, Moisture Sensitivity Level 1, and REACH unaffected status, though these are not verified by documentation. The part number LDL1117S12R suggests a 1.2V output, which conflicts with the 1.185V stated in the product's introductory text.
