®
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 30 pull down on output allows quick discharge of output even under no load
conditions. Both LDOs are protected with current limit and thermal shutdown.
Both LDOs are available in fixed & adjustable output voltage versions and come in an industry standard
SOT-23 5-pin and small 2X3 pin DFN packages. For SC-70 00mA CMOS LDO, SP623 is available.
