LK115D33 Description

Short technical summary and product information.

The STMicroelectronics LK115D33 is a linear voltage regulator designed for low-power applications. It offers a fixed output voltage of 3.3V and can supply up to 100mA of current. Key features include a very low dropout voltage of 0.2V typical and a quiescent current of 0.01µA in off mode, making it ideal for battery-powered systems.

 

This regulator operates over a wide temperature range of -40°C to 125°C and includes internal current and thermal limit protection. It requires only a 2.2µF capacitor for stability, allowing for space and cost savings in designs. The device is available in an 8-SOIC package, suitable for surface mount applications.

 

With its enable control feature, the LK115D33 allows for electronic shutdown, further reducing power consumption when not in use. Its high supply voltage rejection ratio (80 dB typical) ensures stable output performance even with noisy input power sources.
