DESCRIPTION

The 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 I2C bus.

Very low stand-by current consumption is achieved

to specifically comply with entertainment and auto-

motive environments.
