L7986A Description

Short technical summary and product information.

The STMicroelectronics L7986A is a versatile DC-DC switching regulator designed for step-down (buck) applications. It can deliver up to 3A of current and features an adjustable output voltage, making it suitable for a wide range of power management needs.

This component operates with an input voltage starting at 4.5V and a switching frequency adjustable between 250kHz and 1MHz. The device is housed in an 8-HSOP package with an exposed pad, designed for surface mounting. Its operating temperature range spans from -40°C to 150°C (TJ), ensuring reliability in demanding environments.

The L7986A is a non-synchronous buck converter, meaning it utilizes an external diode for rectification. It offers a single positive output configuration. The component's specifications make it a robust choice for various electronic designs requiring efficient voltage regulation.
