The NCP623 low dropout linear regulator can deliver up to 150 mA of output current with a typical dropout voltage of 180 mV. This low dropout feature helps to maintain a regulated output voltage for a longer period of time as the lifetime of the battery decreases. It is the ideal choice for noise sensitive environments like portable applications where noise performance and space are at a premium. The typical output noise voltage specification is 25 mVRMS. The space saving package choices include a Micro8TM or DFN6. An additional noise saving feature of this device is its ability to filter choppy signals on the power supply by providing a typical DC ripple rejection of -90 dB and -70 dB at 1.0 kHz.
