SSC2128

SSC2128 CMOS Low Dropout Elektronische Bauelemente RoHS Compliant Product Voltage Regulator Description The SSC2128 series positive,linear regulators feature low quiescent current (45µA typ.) with low dropout voltage, making them ideal for battery applications. Output voltage are set at the factory and trimmed to 1.5% accuracy.These rugged devices have both Thermal Shutdown and Current Fold-back to prevent device failure under the "Worst" of operating conditions. In applications requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and Ground.The SSC2128 is stable with an output capacitance of 4.7µF or greater.
