TK717xxS is a low dropout linear regulator with a built-in  
electronic switch. The internal switch can be controlled by  
TTL or CMOS logic levels. The device is in the ON state  
whenthecontrolpinispulledtoalogichighlevel.IntheOFF  
state, the output impedance becomes very low, quickly  
dischargingtheoutputcapacitor.Anexternalcapacitorcan  
be connected to the noise bypass pin to lower the output  
noiselevelto30~50mVRMS.AninternalPNPpasstransistor  
is included to achieve a low dropout voltage of 103 mV at  
100 mA load current. The TK717xx has an exceptionally
