LM2576TV-005

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576TV-005 is a monolithic integrated circuit from the LM2576 series, designed as a step-down switching regulator (buck converter). Manufactured by onsemi, this device provides a fixed output voltage of 5.0 V with a guaranteed maximum output current of 3.0 A. It operates with a wide input voltage range from 7 V to 40 V and utilizes an internal fixed-frequency oscillator operating at 52 kHz. The component employs pulse-width modulation (PWM) control for efficient voltage conversion. It is housed in a TO-220-5 through-hole package, suitable for applications requiring robust thermal performance and high current handling capabilities within standard industrial temperature ranges.
