Overview
The LA5632 is a multiple power supply IC that provides
two 3.3-V regulator circuits as well as two 5-V regulator
circuits. This device is optimal for MD players and similar
applications.
Functions and Features
Two built-in 3.3-V regulator circuits (I
O
= 60 mA,
150 mA)
Two built-in 5-V regulator circuits (I
O
= 1000 mA,
100 mA)
Power on/off detection circuit included
The reset circuit operates from the B.BAK voltage.
The reset circuit current drain is extremely low (3.5 A
(typical) in backup mode)
