GENERAL DESCRIPTION
The CapFREE
TM
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
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
V
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
A 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.
APPLICATIONS
Cordless and mobile phones
Industrial and medical equipment
Other battery-powered equipment.
