L7980ATR Description

Short technical summary and product information.

The STMicroelectronics L7980ATR is a versatile DC-DC switching regulator designed for step-down applications. It provides an adjustable output voltage and can handle a current of up to 2A. The device operates with a minimum input voltage of 4.5V and offers a flexible switching frequency range from 250kHz to 1MHz.

 

This regulator is housed in a surface mount package, specifically an 8-SOIC with an exposed pad, and also available in an 8-HSOP. Its adjustable output type and positive output configuration make it suitable for various power management designs. The operating temperature range is from -40°C to 150°C (TJ).

 

Compliance information indicates RoHS3 compliance, MSL 1 unlimited, and REACH unaffected status, though these are based on available database information and may require verification.
