Sanyo LA5632 Specifications

Ordering number : ENN5998

22500RM (OT) No. 5998-1/6

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)
