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 µV
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 µV
RMS
noise without noise bypass capacitor
•Preset output voltages to 2.5 V , 2.8 V, 3.0 V, 3.3 V and 3.6 V;
other voltages available upon request. 2% output voltage
accuracy
•150 mA maximum output current with current limitation
•Typical dropout voltage 55 mV @ 50 mA output current
•85 µA typical ground current
•Thermal-overload and short-circuit protection
•PWROK pin: both power status and thermal warning indicator
•PWRON pin offers logic-controlled shutdown
•Maximum line regulation: 0.1%/V
•Maximum load regulation: 0.02%/mA.
APPLICA TIONS
•Cordless and mobile phones
•Industrial and medical equipment
•Other battery-powered equipment.
