Quality Control: Learn More
The STMicroelectronics L5987 is an adjustable output, 3A monolithic buck switching regulator. This device integrates a high-performance current mode controller with a 3A power MOSFET, operating from a 2.9V to 18V input voltage range. The L5987 features a switching frequency adjustable from 250kHz to 1MHz, enabling optimization for efficiency or component size. Its output voltage is adjustable down to 0.6V, providing design flexibility. The device is housed in an 8-VFQFPN (3x3) package with an exposed pad for enhanced thermal performance, suitable for surface mounting. Applications include automotive power systems, industrial automation, and consumer electronics. The L5987 employs a non-synchronous buck topology.
