Description
The G5U2188 of positive, linear regulator feature low ground current (45ꢀA typ.) with low dropout voltage,
making them 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.
The G5U2188 is stable with an output capacitance of 4.7ꢀF or greater.
