 S2113
CMOS Positive
Elektronische Bauelemente
RoHS Compliant Product
Voltage Regulator
Description
The S2113 series of positive,linear regulators feature low quiescent current (30uA 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 S2113 is stable with an output capacitance of 2.2uF 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.
