BA4908 is a system regulator IC for car stereo.

This IC incorporates 1 channel of 5.6V output,

2 channels of 8.7V output and 2 channels of

high side switch.

1) PNP output and low drop out type (Except AMP and ANT)

2) Built-in output current limit circuit to protect IC from

destruction by short

3) Built-in over-voltage protection circuit to deliver strong

design for surge input to BACK UP and Vcc

4) 12 pin power package perfect for space saving design

5) Built-in thermal protection circuit to protect IC from

thermal destruction
