Overview
The LA5633 is a low-saturation regulator IC designed for
use in satellite broadcast tuners (such as tuners for the
Japanese BS and CS systems) and provides four
controllable outputs.
Applications
Power supply systems in BS/CS tuners
Audio Video (AV) equipment that includes any type of
satellite broadcast tuner
Miniature electronic equipment
Functions
Built-in four regulators of low-saturation output
(15.7 V/350 mA, 9 V/250 mA, 12 V/100 mA,
5 V/650 mA)
Output on/off control (active low)
On-chip thermal protection and overcurrent protection
circuits
Features
Provides all four voltages required by BS/CS tuners, and
thus can contribute to end product miniaturization.
V
O
1 can be controlled independently, and V
O
2, V
O
3,
and V
O
4 are controlled together, thus providing a high
degree of flexibility in system design.
The adoption of a low-saturation regulator circuit
reduces internal power dissipation.
Provides 3 inputs to make both low-power design and
thermal design easy.
