The QX2303L27E with DC-DC converters step-up fixed 1 0.7V 2.7V 2.7V SOT-89 (SOT-89-3) RoHS manufactured by QX Micro Devices is a switching voltage regulator that provides a regulated output voltage of 2.7 volts when input voltages range from 0.7 to 2.7 volts. It is packaged in an SOT-89-3 package, which is designed with 3 pins in a semiconductor package that is RoHS compliant. It is optimized for use in low-profile applications, and it offers low power consumption, low ripple, and high efficiency. It is designed to provide a precise, regulated output voltage that remains constant even when the input voltage drops or rises, making it optimal for applications where the load needs to be supplied with a precisely regulated voltage. It also features over-voltage, over-current, and short-circuit protection, making it highly reliable.
