CapFREE 150 mA, low-noise, low dropout regulator
with thermal protection
SA57000-XX
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
, and an ultra-low dropout voltage
RMS
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
APPLICATIONS
• CapFREE: No output capacitor needed, stable for all capacitive
• Cordless and mobile phones
loads, regardless of ESR
• Industrial and medical equipment
• Other battery-powered equipment.
• Low 30 µV
noise without noise bypass capacitor
RMS
• 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.
