LD2979M50TR Description

Short technical summary and product information.

The LD2979M50TR from STMicroelectronics is a very low drop voltage regulator designed for low power applications. It provides a stable 5V output voltage with an output current capability of up to 50mA. Key features include a very low dropout voltage of 0.2V typical at 50mA load and a low quiescent current of 500µA typical, making it suitable for battery-powered systems.

 

This regulator incorporates logic-controlled electronic shutdown, allowing parts of a board to be put into standby mode to reduce power consumption. It also features internal current and thermal limit protection. The device requires only a 1µF capacitor for stability and operates over a temperature range of -25°C to 125°C.

 

The LD2979M50TR is available in a SOT-23-5L package, suitable for surface mount applications. Its design considerations include low noise and low power requirements, making it ideal for portable electronics and other power-sensitive devices.
