Power Supply IC for Microcomputer
LC201S
General Descriptions
LC201S is the power supply IC for microcomputer of
lighting, incorporating a start up circuit and a linear
regulator.
There are two outputs. The output voltage of OUT1 can
be switched 9 V or 20 V. The output voltage of OUT2 is
5V. The product achieves high cost-performance power
supply systems with few external components for
microcomputer.
Features
 Built-in startup circuit
 Power dissipation of the startup circuit is zero.
(When the power of IC is supplied from external
power supply)
 OUT1 pin voltage is selectable from 9 V or 20 V by
SL pin voltage.
(When the power of IC is supplied from internal
startup circuit)
 OUT2 voltage is fixed to 5V
 Current Sink Function
(In case OUT1 pin voltage decreases, OUT2 pin is
fixed to Low state)
