SM2123
CMOS Positive
Voltage Regulator
Description
The SM2123 series of positive,linear regulators feature low quiescent
current (30µA typ.) with low dropout voltage, making them ideal
for battery applications. These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the "Worst" of
operating conditions. The SM2123 is stable with an output capacitance of
2.2µF or greater.
