L7985TR Description

Short technical summary and product information.

The STMicroelectronics L7985TR is a versatile step-down (buck) voltage regulator designed for power management applications. It features an adjustable output voltage ranging from 0.6V to 38V, with a maximum output current capability of 2A. The device accepts an input voltage between 4.5V and 38V, making it suitable for a wide array of power supply designs.

 

This regulator operates with a switching frequency between 250kHz and 1MHz, offering flexibility in component selection and efficiency optimization. It is configured for positive output and does not utilize a synchronous rectifier. The operating temperature range is -40°C to 150°C (TJ), ensuring reliable performance in various thermal environments.

 

The L7985TR is available in a 10-VFDFN Exposed Pad package, designed for surface mounting. This packaging type facilitates efficient heat dissipation and compact board layouts. The component is supplied in Cut Tape (CT) & Digi-Reel® packaging formats.
