RT9078-18GQZ

LDO电压稳压器, 固定, 1.2 V至5.5 V输入, 1.8 V/300 mA输出, 240 mV压差, QFN-4

The from is a 300mA low dropout LDO linear regulator without SNS output voltage sense pin in 4 pin ZQFN package. This regulator with enable function operates from 1.2V to 5.5V. It provides up to 300mA of output current and offers low power operation in miniaturized packaging. The features of low quiescent current as low as 2µA and almost zero disable current is ideal for powering the battery equipment to a longer service life. The RT9078 is stable with the ceramic output capacitor over its wide input range from 1.2V to 5.5V and the entire range of output load current 0mA to 600mA. The minimum required output capacitance for stable operation is 1µF effective capacitance after consideration of the temperature and voltage coefficient of the capacitor.
