Monolithic Linear IC
Multiple Voltage Power Supply
The LA5603 is a multifunction, low dropout voltage, mul-
tiple 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 (IOA2=0.1A, IOA1=0) supply with a reverse
current prevention diode and a 5.6V (IOA1=0.1A, IOA2=0)
supply enabling it to power both analog and digital compo-
The LA5603 incorporates reset, mute and power-on func-
tions for generating signals for the components (s) being
powered and an adjustable startup delay function for con-
trolling the sequence in which system components are pow-
ered up.
The LA5603 operates from a ±8.5 to ±16V dual supply
and is available in 18-pin SIPs.
