LA5606N
BS/CS Tuner Regulator with On/Off Function
Overview
The LA5606N is a low saturation regulator IC for BS/CS tuner applications, equipped with four regulators capable of ON/OFF control.
Package Dimensions
unit: mm 3023A-SIP14H
[LA5606N]
Applications
* BS/CS tuner power supply system. * Audio Video (AV) equipment with BS/CS receivers. * Compact electronic equipment.
Functions
* Four low saturation regulators (15.7 V/300 mA, 12 V/150 mA, 9 V/100 mA and 5 V/500 mA). * Output on/off control ("L" active). * On-chip protective circuitry (current limiter, thermal shutdown).
Features
* Supports compact set design while incorporating four regulators needed by BS/CS tuners. * Flexible system design by independent on/off control of VO1, VO4, as well as VO2 and VO3 pair. * Reduces internal loss by employment of low saturation regulators. * Adapting three input pins contributes power dissipation reduction and heat sink design.

LA5606N Notes for Above Applications 1. GND1 and GND2 should be at the same electric potential; since these are connected to the substrate of the LA5606N, the lowest possible electric potential should be used. (If the electric potential of GND1 and GND2 differ, performance characteristics of the LA5606N can not be guaranteed.) 2. Rise and fall times for VIN1, VIN2 and VIN3 should be unified and concerning these pins operating in an opencircuit state or connected to the ground state is forbidden. 3. When VIN1 and VIN2 are open or lower than the required value, VO1 to VO4 are forced off for the IC's protection. 4. Use output capacitors COUT1 and COUT4 rated at 100 F or more and COUT2 and COUT3 rated at 47 F or more. To prevent oscillation at low temperature, be sure to use less temperature sensitive capacitors. 5. In order to provide stable operation, CIN1 to CIN3 and COUT1 to COUT4 should be mounted as close to the LA5606N as possible. 6. The NC pins should not be used (No. 1 and No. 14 in the pin layout). 7. The output voltage of each voltage regulator is affected by a change in the load on the other voltage regulators.
