S5U2179
CMOS
Low Dropout
Elektronische Bauelemente
RoHS Compliant Product
Voltage Regulator
Description
The S5U2179 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 S5U2179 is stable with an output capacitance
of 4.7µF or greater.
