RT9080-18GQZ Richtek

RT9080 2A I , 600mA Low-Dropout Linear Regulator Q General Description Features 2A Ground Current at no Load The RT9080 is a low-dropout (LDO) voltage regulators with PSRR = 75dB at 1kHz enable function that operates from 1.2V to 5.5V. It provides Adjustable Output Voltage Available by Specific up to 600mA of output current and offers low-power Application operation in miniaturized packaging. 2% Output Accuracy The features of low quiescent current as low as 2A and 600mA (V 2.3V) Output Current with EN IN almost zero disable current is ideal for powering the battery Low (0.1A) Disable Current equipment to a longer service life. The RT9080 is stable 1.2V to 5.5V Operating Input Voltage with the ceramic output capacitor over its wide input range Dropout Voltage : 0.31V at 600mA when V 3V OUT from 1.2V to 5.5V and the entire range of output load Support Fixed Output Voltage 0.8V to 3.3V current (0mA to 600mA).
