The LM3102MHX/NOPB is a 2.5A Step-Down Voltage Regulator from Texas Instruments designed to provide an adjustable output voltage, flexibility, low quiescent current, and high efficiency. It is constructed with a dual-mode buck topology that provides both constant voltage and constant current output regulation. The ability to switch from fixed output voltage to constant current mode makes the LM3102MHX/NOPB an ideal solution for LED driver applications. The SIMPLE SWITCHER family includes SOT-23, SOIC, and the ultra-small 20-HTSSOP, allowing space savings on the printed circuit board and optimizing device performance. With wide input voltage and operating temperature ranges of -40°C to 125°C, the LM3102MHX/NOPB is suitable for a variety of automotive applications, as well as industrial, medical, and consumer applications.
