LC201S

LC201S is a power supply IC for a microcontroller. It is a linear regulator with a startup circuit.
Available in 2 types of output. Output 1 (Output of 9 V (Typ.) or 20 V (Typ.), and Output 1 (Output of 5V(Typ.))
Power supply for microcontrollers can be easily constructed with only a few external components.

Features

    ・Integrated start-up circuit (Reduces number of external components)
    ・Power consumption of the startup circuit is zero (with auxiliary winding)
    ・Output voltage OUT1:
     Output of 9 V (Typ.) or 20 V (Typ.) .
     When auxiliary winding isconnected to OUT1 pin, OUT1 pin is power supply of the control circuit.
    ・Output voltage OUT2: Output of 5 V (Typ.) (for microcontroller)
    ・UVLO (Under Voltage Lockout) function
     (If OUT1 pin voltage decreases, OUT2 pin fixed to Low state)

Application

    ・Lighting equipment
     Fluorescent lights, Ceiling lights, street lights, Down lights, etch
    ・Other equipments using microcomputers
