CMOS Low Dropout Voltage
Regulator
RoHS Compliant Product
Elektronische Bauelemente
Description
The S5U2178 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 S5U2178 is stable with an output capacitance of 4.7µF or greater.
Features
