Description
The GL2146 series of positive, linear regulators feature low quiescent current (30ꢀA 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 GL2146 is stable with an output capacitance of 2.2ꢀF 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: VIN (MIN) =VOUT+VDROPOUT
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.
