Description
The GQ2143 of positive, linear regulators feature low quiescent current (35 A typ.) with low dropout voltage,
making them ideal for battery applications.
This rugged device has both Thermal Shutdown, and Current Fold-back to prevent device failure under the
“Worst” of operating conditions.
The GQ2143 is stable with an output capacitance of 2.2 F or greater.
