Description
The G5U2167 series of positive, linear regulators feature low quiescent current (45ꢀA typ.) with low dropout
voltage, making then ideal for battery applications.
Output voltages 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.
An additional feature is a “Power Good” detector, which pulls low when the output is out of regulation.
The G5U2167 is stable with an output capacitance of 4.7ꢀF or greater.
