LK112SM18TR Description

Short technical summary and product information.

The STMicroelectronics LK112SM18TR is a linear voltage regulator IC, suitable for applications requiring a stable voltage supply. It features a fixed 1.8V output voltage and can deliver up to 200mA of current. The device operates within a temperature range of -40°C to 125°C and includes protection features such as over current and over temperature.

 

This regulator is housed in a SOT-23-5 package, making it ideal for surface mount applications where space is a constraint. Its positive output configuration and enable control feature offer flexibility in circuit design. The PSRR of 55dB at 400Hz indicates good noise rejection capabilities.

 

With a quiescent current of 250 µA, the LK112SM18TR is designed for power-sensitive applications. It is RoHS3 compliant and has a Moisture Sensitivity Level (MSL) of 1, indicating its suitability for a wide range of manufacturing environments.
