S5U2187
750mA CMOS Positive Voltage Regulator
RoHS Compliant Product
Elektronische Bauelemente
Description
The S5U2187 of 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 S5U2187 is stable with an output capacitance of 4.7µF or greater.
Features
