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
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)
and a 5-bump Wafer Level Chip-Scale package (WL-CSP5). 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.

DESCRIPTION
Regulator input. V
OUT(nom)
+ 0.5 V to 6.5 V. No bypass capacitor required.
Ground.
Power-on input. Active-HIGH. A logic LOW powers down the regulator. The shutdown quiescent current is
typically 50 nA. Connect to V
IN
for manual operation.
Power OK indicator, including thermal warning. Connect a 10 kΩ resistor between PWROK and V
OUT
.
Active-LOW open-drain output indicates an out-of-regulation condition when power falls typically 6% below
VOUT(nom), or thermal warning (trips at 127
°C ±
2
°C).
Regulator output. Sources up to 150 mA. No bypass capacitors required.
