钰泰半导体 ETA5254 双通道LDO稳压器芯片

　　DESCRIPTION

　　ETA5254 is a dual channel, low-dropout (LDO) low-power linear voltage regulator that features high power-supply rejection ratio (PSRR), ultralow-noise, fast start-up, and excellent line and load transient responses. Its PSRR can be as high as 60dB with quiescent current is about 35uA for each channel.

　　Each individual LDO channel has its own enable pin and output voltage target, resulting in greatly reduced power consumption and enhanced PCB design flexibility. It also has other features include current limit and thermal shutdown protection.

　　ETA5254 is available in SOT23-6.
