SN2133
RoHS Compliant Product
Voltage Regulator
Description
SN2133 series positive,linear regulators feature quiescent current (30µA typ.) with dropout voltage, making them ideal battery applications. These rugged devices have both Thermal Shutdown, Current Fold-back prevent device failure under "Worst" operating conditions. SN2133 stable with output capacitance 2.2µF greater.
