L7986TA Description

Short technical summary and product information.

The STMicroelectronics L7986TA is a versatile step-down (buck) switching regulator. It is designed to provide an adjustable output voltage and can handle a maximum output current of 3A. The device operates from a 4.5V input voltage and features a switching frequency range of 250kHz to 1MHz, allowing for flexibility in design and component selection.

 

This regulator is housed in an 8-HSOP-EP package with surface mount capability, making it suitable for various electronic designs. The adjustable output configuration provides design freedom, while the positive output type ensures compatibility with common power supply architectures. Its step-down topology is efficient for reducing higher input voltages to lower output voltages.

 

The operating temperature range for the L7986TA is -40°C to 150°C (TJ), ensuring reliable performance in a variety of environmental conditions. It is classified as a PMIC (Power Management Integrated Circuit) and falls under the category of DC-DC Switching Regulators.
