lose regulation or when the short circuit or thermal overload
protection is activated. Other features include shutdown and
optional noise reduction capabilities. T he ADP330x anyCAP
LDO family offers a wide range of output voltages and output
current levels from 50 mA to 300 mA:
T he ADP3307 is a member of the ADP330x family of precision
low dropout anyCAP voltage regulators. T he ADP3307 stands
out from the conventional LDOs with a novel architecture and
an enhanced process. Its patented design requires only a 0.47 µF
output capacitor for stability. T his device is stable with any type
of capacitor regardless of its ESR (Equivalent Series Resistance)
value, including ceramic types (MLCC) for space restricted
applications. T he ADP3307 achieves exceptional accuracy of
±0.8% at room temperature and ±1.4% overall accuracy over
temperature, line and load regulations. T he dropout voltage of
the ADP3307 is only 120 mV (typical) at 100 mA.

T he ADP3307 operates with a wide input voltage range from
3.0 V to 12 V and delivers a load current in excess of 100 mA.
