GENERAL DESCRIPTION
The ADP3307 is a member of the ADP330x family of precision
low dropout anyCAP voltage regulators. The 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. This device is stable with any type
of capacitor regardless of its ESR (Equivalent Series Resistance)
value, including ceramic types (MLCC) for space restricted
applications. The ADP3307 achieves exceptional accuracy of
± 0.8% at room temperature and ± 1.4% overall accuracy over
temperature, line and load variations. The dropout voltage of
the ADP3307 is only 120 mV (typical) at 100 mA.
The 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.
It features an error flag that signals when the device is about to
100 mA Low Dropout Linear Regulator
lose regulation or when the short circuit or thermal overload
protection is activated. Other features include shutdown and
optional noise reduction capabilities. The ADP330x anyCAP
LDO family offers a wide range of output voltages and output
current levels from 50 mA to 300 mA:

ADP3300 (50 mA, SOT-23-6)
ADP3307 (100 mA, SOT-23-6)
