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

µVRMS, 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.

APPLICATIONS

• Cordless and mobile phones

• Industrial and medical equipment

• Other battery-powered equipment.
