UL9480

DESCRIPTION 

The UTC UL9480 is a specially designed voltage regulator for 

car alternator. The regulator voltage is precise with “single function”

self-oscillation. These devices have a maximum output current of 

5.5 A. The chip is integrated both the control section and the out 

power stage. So the devices require no external components, 

reducing the cost of the system and increasing reliability. 

FEATURES
