LK115D50 Description

Short technical summary and product information.

The STMicroelectronics LK115D50 is a low dropout (LDO) linear voltage regulator designed for low-power applications. It provides a fixed output voltage of 5V and can supply up to 100mA of current. Key features include a very low dropout voltage of 0.2V typical and low quiescent current, making it suitable for battery-powered systems.

 

The regulator operates over a wide temperature range of -40°C to 125°C and has internal current and thermal limit protection. It requires only a small external capacitor (2.2µF) for stability. The device is housed in an 8-SOIC package, suitable for surface mounting.

 

With its enable control feature and protection mechanisms, the LK115D50 offers reliable voltage regulation for various electronic designs. Its specifications include a maximum input voltage of 20V and a PSRR of up to 75dB.

 

This component is ideal for applications requiring stable, low-noise power supply with minimal voltage drop. The surface mountable 8-SOIC package facilitates integration into compact circuit designs.
