LD2985BM18R Description

Short technical summary and product information.

The LD2985BM18R is a linear voltage regulator from STMicroelectronics designed to deliver a fixed output voltage of 1.8V with a maximum output current of 150mA. This device is housed in a compact SOT-23-5 package, making it suitable for space-constrained applications.

 

As a linear regulator, it provides a stable and low-noise output voltage, ideal for powering sensitive analog and digital circuits. The fixed 1.8V output eliminates the need for external resistor dividers, simplifying design and reducing component count.

 

The SOT-23-5 package offers a small footprint while providing adequate thermal performance for the 150mA current rating. This regulator is commonly used in battery-powered devices, portable electronics, and other applications requiring a regulated low-voltage supply.
