The noise performance is achieved by means of an external bypass capacitor without MP3/CD Players sacrificing turn-on and turn-off speed critical Digital Cameras to portable applications. Extremely stable and easy to use, these devices offer excellent PSRR and Line/Load regulation. Target FEATURES applications include battery-powered 300mA/500mA Output Current equipment such as portable and wireless SP6203: 300mA SP6205: 500mA products. Regulators ground current increases only slightly in dropout. Fast turn-on/turn-off Low Dropout Voltage: 0.6 PMOS FET enable control and an internal 30 pull down 2.7V to 5.5V Input Voltage on output allows quick discharge of output Fixed and Adjustable Output Voltage even under no load conditions. Both LDOs are protected with current limit and thermal Accurate Output Voltage: 2% over Temp. shutdown. 67dB Power Supply Rejection Ratio The SP6205 is available in fixed & adjustable 12VRMS Low Output Noise output voltage versions and come in an industry standard 5-pin SOT-23 and small Unconditionally Stable with 2.2F 2X3mm 8-pin DFN packages. For SC-70 Ceramic 100mA CMOS LDO, SP6213 is available. Low Quiescent Current: 45A Low Ground Current: 350A at 500mA Fast Turn-On and Turn-Off: 60S Very Good Load/Line Regulation: 0.07/0.04 % Current Limit and Thermal Protection RoHS Compliant Green/Halogen Free 5-Pin SOT23 and 8-Pin DFN Packages TYPICAL APPLICATION DIAGRAM Fig. 1: SP6203/SP6205 Application Diagram 1 SSPP66220033 // SSPP66220055 330000mmAA//550000mmAA LLooww NNooiissee CCMMOOSS LLDDOO RReegguullaattoorrss ABSOLUTE MAXIMUM RATINGS OPERATING RATINGS These are stress ratings only and functional operation of Input Voltage Range VIN .......................... +2.7V to +5.5V the device at these ratings or any other above those Enable Input Voltage V ..............................0 to 5.5V EN indicated in the operation sections of the specifications Junction Temperature Range ................. -40C to +125C below is not implied.
