GJ2148
1.5A CMOS Low Dropout Voltage Regulator
Description
The GJ2148 series of positive, linear regulators feature low quiescent current (45 A 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 GJ2148 is stable with an output capacitance of 4.7 F or greater.
