LDLN015xx is an ultra low noise linear regulator which provides 150mA maximum current from an input voltage ranging from 2.1 V to 5.5 V with a typical dropout voltage of 86 mV. The LDLN015xx provides a very clean output suitable for ultra sensitive loads with its 6.3µVRMS noise value in a band from 10 Hz to 100 kHz. It is stable with ceramic capacitors and suitable for low power battery powered applications.
