LC201S

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) Typical Application Circuit VAC BR1 87 65 C1 ST NC NC OUT1 U1 LC201S GND SL SINK OUT2 1234 C2 Micro computer R1 C3 Package SOP8 Not to scale Applications  Various lig...
