The QX7135E38 LED Driver with SOT-89-3 RoHS manufactured by QX Micro Devices is a power supply integrated circuit (IC) which helps regulate and boost current to power light emitting diodes (LEDs). It can accept input voltages ranging from 3V - 13V and can output up to 175mA of current. It features low dropout voltage (typically 0.35V) for greater efficiency and is small and lightweight thanks to its SOT-89-3 RoHS package. The QX7135E38 is ideal for automotive, industrial, telecom, consumer electronics, and computer applications.
