Description	Micropower/ 150mA Ultra Low-Dropout CMOS Voltage Regulator
Datasheet	LP3988_NationalSemiconductor.pdf

The LP3988 is a 150mA low dropout regulator designed specially to meet requirements of Portable batteryapplications.

an Error Flag output that indicates a faulty output condition. The LP3988’s performance is optimized for battery powered systems to deliver low noise, extremely low dropout voltage and low quiescent current. Regulator ground current increases only slightly in dropout, further prolonging the battery life. Power supply rejection is better than 60 dB at low frequencies and starts to roll off at 10 kHz. High power supply rejection is maintained down to lower input voltage levels common to battery op.
