FC2129 CMOS Low Dropout Voltage ( LDO ) Regulator
CMO S L ow Drop out Vo ltag e Reg ul ato r
Description
The FC2129 series of positive, linear regulators feature low quiescent current (45 A typ.) with low dropout
voltage, making them ideal for battery applications.
Output voltages are set at the factory and trimmed to 1.5% accuracy.
These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under
the “Worst” of operating conditions.
In applications requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and Ground.
The FC2129 is stable with an output capacitance of 4.7 F or greater.
