NCP2990 Features

* a low

* power consumption shutdown mode, which is achieved by driving the SHUTDOWN pin with logic low. The NCP2990 contains circuitry to prevent from “pop and click” noise that would otherwise occur during turn

* on and turn

* off transitions. It is a zero pop noise device when a s
