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
speed critical to portable applications. Extremely stable and easy to use, these devices offer excellent PSRR
and Line/Load regulation. Target applications include battery-powered equipment such as portable and
wireless products. Regulators' ground current increases only slightly in dropout. Fast turn-on/turn-off enable
control and an internal 301 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.
