L4971D013TR Description

Short technical summary and product information.

The STMicroelectronics L4971D013TR is a versatile DC-DC switching regulator designed for step-down (buck) applications. This adjustable output voltage regulator can provide a stable output current of up to 1.5A. It operates with an input voltage of 8V and features a switching frequency range between 100kHz and 300kHz.

The device utilizes a non-synchronous rectifier topology and is configured for positive output voltage. It is housed in a 16-SOIC package, requiring surface mount installation. The operating temperature range is from -40°C to 150°C (TJ), making it suitable for various environmental conditions.

This component is ideal for power management circuits where efficient voltage conversion is required. Its adjustable output capability allows for flexibility in design, while the 1.5A current rating supports a range of power requirements.
