GENERAL DESCRIPTION
The CapFREE
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
μ
V
RMS
, 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).
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.
FEATURES
CapFREE: No output capacitor needed, stable for all capacitive
loads, regardless of ESR
Low 30
