LD2979M30TR Description

Short technical summary and product information.

The STMicroelectronics LD2979M30TR is a very low drop voltage regulator designed for low noise and low power applications, particularly in battery-powered systems. It provides a fixed output voltage of 3.0V with a maximum output current of 50mA.

 

Key features include a very low dropout voltage of 0.2V typical at 50mA load and a very low quiescent current of 500µA typical at 50mA load. The device also incorporates logic-controlled electronic shutdown, allowing parts of a board to be put into standby to decrease power consumption. It offers internal current and thermal limit protection and a supply voltage rejection of 63dB typical.

 

The regulator is available in a compact SOT-23-5L package, suitable for surface mounting. It requires only a 1µF capacitor for stability. The operating temperature range is -25°C to 125°C.

 

This series is suitable for applications requiring stable voltage regulation with minimal power dissipation, such as portable electronics and battery-operated devices.
