L5987A Description

Short technical summary and product information.

The STMicroelectronics L5987A is a versatile DC-DC switching regulator with a step-down (buck) topology. It is designed to provide an adjustable output voltage and can handle up to 3A of current. The device operates with a 2.9V input voltage and offers a wide switching frequency range from 250kHz to 1MHz, allowing for flexibility in design.

 

This regulator is suitable for applications requiring efficient power conversion. It features a positive output configuration and is not a synchronous rectifier. The component is housed in an 8-HSOP package with an exposed pad, designed for surface mounting. Its operating temperature range is from -40°C to 150°C (TJ), making it suitable for various environmental conditions.

 

The L5987A is RoHS3 compliant and has an MSL rating of 1 (unlimited). Its REACH status is unaffected. This component is ideal for power management in electronic devices where efficient and adjustable voltage regulation is needed.
