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 (IO= 60 mA,
150 mA)
• Two built-in 5-V regulator circuits (IO= 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 µA
(typical) in backup mode)
