Overview
The LA5603 is a multifunction, low dropout voltage, multiple voltage power supply for use in microcomputer
controlled audio equipment such as CD players and
minicomponent stereo systems.
The LA5603 features a 5.6V, 0.5A supply, a 7.5V, 1.0A
supply and a –7.5V, –1.0A supply each with an on/off
switch, a 4.8V (I
OA2
=0.1A, I
current prevention diode and a 5.6V (I
supply enabling it to power both analog and digital components.
The LA5603 incorporates reset, mute and power-on functions for generating signals for the components (s) being
powered and an adjustable startup delay function for controlling the sequence in which system components are powered up.
The LA5603 operates from a ±8.5 to ±16V dual supply
and is available in 18-pin SIPs.
