SSC2139

SSC2139 1.55A CMOS Elektronische Bauelemente RoHS Compliant Product Low Dropout Voltage Regulator Description The SSC2139 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.The SSC2139 is stable with an output capacitance of 4.7µF or greater. Features * Low Temperature Coefficient * Over-Temperature Shutdown * Adjustable Version * Very Low Dropout Voltage * High Accurate ± 1.5% * Guaranteed 1.55A output * Current Limiting * Power-Saving Shutdown Mode REF.
