LD2981ABM25TR Description

Short technical summary and product information.

The STMicroelectronics LD2981ABM25TR is a CMOS linear voltage regulator designed to provide a stable 2.5V output. It can deliver up to 100mA of current with a low dropout voltage of 0.375V at 100mA. The device features a low quiescent current of 150µA, making it suitable for power-sensitive applications. Its high Power Supply Rejection Ratio (PSRR) of 63dB at 1kHz helps filter out noise from the power supply, making it ideal for use after DC-DC converters.

 

The LD2981ABM25TR operates within a temperature range of -40°C to 125°C. It is housed in a SOT-23-5 surface-mount package, offering a small footprint for compact designs. The enable pin allows for easy control of the output, and the device is suitable for applications such as USB peripherals, portable devices, and IoT modules where efficient power management is crucial.
