The LM2596T-3.3 with DC-DC Converters TO-220 RoHS is an efficient 4.0 to 40 volt output step-down voltage regulator with a fixed 3.3V output. It offers a wide input voltage range of 4.0V to 40V, allowing the use of unregulated discrete, wall adapters, or battery sources. This product is designed to offer a very low dropout voltage operation at 0.5V which achieves higher efficiency with 5V to 40V input range. It has a high conversion efficiency of up to 96%, ensuring low energy consumption with minimal heat dissipation. In addition, the operation of the device is synchronized, which ensures noise-free operation. This device is great for a variety of battery powered and other low voltage applications such as handheld electronic devices, consumer electronics, instruments, and point of sale machines. It is RoHS compliant, and is manufactured by Huaguan.
