CMOS Positive
Elektronische Bauelemente
RoHS Compliant Product
Voltage Regulator
Description
The
SM2114 series of positive,linear regulators feature low quiescent
current (30µA typ.) with low dropout voltage, making them ideal
f
or battery applications. These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the "Worst" of
operating conditions. The SM2114 is stable with an output capacitance of
2.2µF or greater.
