PJ9570M12DFC

PJ9570 Series Low Dropout Regulators Description SOT-23 3.VIN The PJ9570 Series are highly precise,low noise,positive voltage LDO regulators manufactured using CMOS processes. The PJ9570 performance is optimized for battery-powered systems to deliver ultra low noise and low quiescent current. Regulator ground current increases only slightly in dropout, further prolonging the 1.GND 2.VOUT battery life. The PJ9570 Series also works with low-ESR ceramic capacitors, SOT-23-3 reducing the amount of board space necessary for power applications, critical in 3.VIN hand-held wireless devices. The PJ9570 Series consumes less than 1μA in shutdown mode and has fast turn-on time less than 50s. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio.
