Description
E
S1
The S2123 series of positive,linear regulators feature low quiescent
current (30mA typ.) with low dropout voltage, making them ideal
for battery applications. These rugged devices have both Thermal Shutdown,
b1
SEATING
PLANE
and Current Fold-back to prevent device failure under the "Worst" of
operating conditions. The S2123 is stable with an output capacitance of
2.2mF 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.
