DESCRIPTIONThe L5952 is a multifunction 5 output voltage regula-
tor plus a High Side Driver primarily developed for car
radio applications.
Three outputs are enabled and set via I2 C bus.
Very low stand-by current consumption is achieved
to specifically comply with entertainment and auto-
motive environments.
