GENERAL DESCRIPTION
The ADP3300 is a member of the ADP330x family of precision
low dropout anyCAP™ voltage regulators. The ADP3300
stands out from 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 capacitor, regardless of its ESR (Equivalent Series Resistance)
value, including ceramic types (MLCC) for space restricted appli-
cations. The ADP3300 achieves exceptional accuracy of ±0.8%
at room temperature and ± 1.4% overall accuracy over tempera-
ture, line and load regulations. The dropout voltage of the
ADP3300 is only 80 mV (typical) at 50 mA.
The ADP3300 operates with a wide input voltage range from
3.0 V to 12 V and delivers a load current in excess of 50 mA. It
features an error flag that signals when the device is about to
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™
