DESCRIPTION
The L4952 is a monolithic voltage regulator in an
advanced BCD60II process with high efficient p-
channel transistor. This device is optimized for
Car Radio applications to obtain optimum per-
formance and supply system integration with high
flexibility and minimum peripheral components.
