LK112M33TR Description

Short technical summary and product information.

The STMicroelectronics LK112M33TR is a linear voltage regulator IC designed to provide a stable 3.3V output voltage with a maximum current capability of 150mA. It features a low dropout voltage of 0.35V at 150mA and operates over a temperature range of -30°C to 125°C.

 

This device is suitable for various power management applications requiring a reliable and efficient voltage regulation. It includes protection features such as over-current and over-temperature protection, enhancing its robustness in demanding environments. The regulator also offers an Enable control feature for power management.

 

The LK112M33TR is supplied in a compact SOT-23-5 surface mount package, making it ideal for space-constrained designs. Its other package options include SC-74A and SOT-753. The component is designed for positive output configuration and has a PSRR of 55dB at 400Hz.

 

Key electrical characteristics include a maximum input voltage of 14V and a single regulator output. The component's compliance status for RoHS is listed as RoHS3 Compliant, Moisture Sensitivity Level (MSL) is 1, and REACH status is Unaffected, though these are noted as low confidence.
