SL9193M36SA Linear Voltage Regulators (LDO) SOT-23

The SL9193 Series are highly precise,low noise,positive voltage LDO regulators manufactured using CMOS processes. The SL9193 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 battery life. The SL9193 Series also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical in hand-held wireless devices. The SL9193 Series consumes less than 1μA in shutdown mode and has fast turn-on time less than 50μs. The other features include ultra low dropout voltage, high output accuracy, current limiting protection, and high ripple rejection ratio.
