STMicroelectronics L7980A is a 2A adjustable positive buck switching regulator. This device offers a wide input voltage range from 4.5V to 28V and an output voltage adjustable from 0.6V up to 28V, with a maximum output current of 2A. The L7980A operates with a switching frequency that can be set between 250kHz and 1MHz, enabling efficient power conversion. Its 8-HSOP package with an exposed pad facilitates effective thermal management, crucial for high-current applications. The non-synchronous buck topology ensures a robust and reliable step-down conversion. Operating temperature range is -40°C to 150°C (TJ). This component is widely employed in automotive, industrial automation, and power supply applications where efficient voltage regulation is paramount.
