DESCRIPTION  
The SP6203/6205 are ultra low noise CMOS LDOs with very low dropout and ground current. The noise  
performance is achieved by means of an external bypass capacitor without sacrificing turn-on and turn-off  
speedcriticaltoportableapplications.Extremelystableandeasytouse,thesedevicesofferexcellentPSRR  
and Line/Load regulation. Target applications include battery-powered equipment such as portable and  
wirelessproducts.Regulators'groundcurrentincreasesonlyslightlyindropout.Fastturn-on/turn-offenable  
control and an internal 30pull down on output allows quick discharge of output even under no load  
conditions. Both LDOs are protected with current limit and thermal shutdown.  
Both LDO's are availiable in fixed & adjustable output voltage versions and come in an industry standard  
5 pin SOT-23 and small 8 pin DFN package. For SC-70 100mA CMOS LDO, SP6213 is available.
