Descriptions  
The WL2862K series is a high accuracy, high input  
voltage low quiescent current, high speed, and low  
dropout Liner regulator with high ripple rejection.  
SOT-89  
The WL2862K offers over-current limit and over  
temperature protection to ensure the device working in  
well conditions.
