RoHS Compliant Product
S5U2189
1.55A CMOS
Low Dropout Voltage Regulator
Description
The S5U2189 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 S5U2189 is stable
with an output capacitance of 4.7µF or greater.
