Description
The GN2133 series of positive, linear regulators feature low quiescent current (30 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 GN2133 is stable with an output capacitance of 2.2 F or greater.

Note 1: VOUT (E) =Effective Output Voltage (i.e. the output voltage when “VOUT (T) +1.0V” is provided at the VIN pin while maintaining a
certain IOUT value).
2: VOUT (T) =Specified Output Voltage
3: V IN (MIN) =VOUT+V DROPOUT
4: To prevent the Short Circuit Current protection feature from being prematurely activated, the input voltage must be applied before
a current source load is applied.
