The CapFREEE SA57000 is the first in a new family of unique low dropout regulators. It needs no external capacitors, offers a low output noise voltage of 30 mVRMS, and an ultra-low dropout voltage of 55 mV @ 50 mA output current. To accommodate high density layouts, SA57000 is packaged in the small footprint 5 leaded SOT23-5 (SO5). It is ideal for all portable and cellular phone applications.

Additional features of SA57000 include power and thermal shutdown, output current limitation, power OK status, thermal warning, and external logic-controlled on-off via the PWRON pin.
