LA5603
Multifunction, Multiple Voltage Power Supply
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 (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 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.

Design Notes When the 5.6 (VO1), 7.5 and 7.5V output are ON, EN is high impedance. When QUICK IN is HIGH, mute mode is ON. When QUICK IN is LOW, mute mode is OFF. The output capacitors for VO1, VOA1, and VOA2 should be 47µF or greater. The output capacitors for VO2 and VO3 should be 100µF or greater. The output capacitors and Cd, the startup delay capacitor, should have good temperature stability to prevent oscillations at low temperatures. Capacitors CN1, CN2, CN3 and CNA suppress noise and improve ripple rejection.
