August 2004 www.DataSheet4U.com LP3994 50mA CMOS Voltage Regulator with Enable Control LP3994 50mA CMOS Voltage Regulator with Enable Control General Description The LP3994 regulator provides 1.5V and 1.8V outputs options at up to 50mA load current. The LP3994 provides an accurate output voltage with low quiescent current at full current. Good noise performance is obtained without a noise bypass capacitor. The low quiescent current in operation can be reduced to virtually zero when the device is disabled via a logic signal to the enable input. In conjuction with small space saving capacitors, the small package size of the microSMD devices results in a regulator solution with a very small footprint for any given application.
