The RT9041E-12GQW is a low dropout linear regulator designed to provide a fixed output voltage ranging from 1V to 2V in 0.1V increments, with adjustable output voltage available through external resistors. It supports input supply voltages from 1V to 5.5V and requires a bias supply voltage between 3V and 5.5V. The device features a maximum output current of 500mA, with a low quiescent current of 160µA and a shutdown current of 1µA. It includes protection features such as current limit and thermal shutdown to safeguard against fault conditions. The regulator is housed in a compact WDFN-8L 2x2 package and is compliant with RoHS standards, making it suitable for various applications including set-top boxes, notebook computers, and cell phones.
