The CapFREETMSA57000 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 uVRMS, and an ultra-low dropout voltage of 55 mV @ 50 mA output current. To accommodate high density layouts, it is packaged in the small footprint 5 leaded SOT23-5 (SO5) and a 5-bump Wafer Level Chip-Scale package (WL-CSP5). It is ideal for all portable and cellular phone applications.
Additional features include power and thermal shutdown, output current limitation, power OK status, thermal warning, and external logic-controlled on-off via the PWRON pin.
