The LM2576S-ADJ with DC-DC Converters TO-263 RoHS is a step-down switching regulator manufactured by Youtai. It is a monolithic integrated circuit capable of delivering up to 5A of output current. It has a wide operating voltage range of 4.5V to 40V and can provide an adjustable output from 1.5V to 37V. It also features a low quiescent current of 100uA. This converter provides excellent line and load regulation and is well-suited for locally powering sensitive loads from a higher voltage source. It also implements various protection features, including thermal shutdown, current limit, internal short circuit protection, virtual current sensing, and is designed for limited continuous output power dissipation. The TO-263 RoHS package provides an ultra-small solution for space-constrained applications.
