Sanyo LA5603 Specifications

Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.

SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other

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.

Design Notes

When the 5.6 (V

), 7.5 and –7.5V output are ON, EN is high impedance.

O1

When QUICK IN is HIGH, mute mode is ON. When QUICK IN is LOW, mute mode is OFF.
The output capacitors for VO1, V

OA1

, and V

should be 47µF or greater. The output capacitors for VO2 and V

OA2

O3

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.
