GENERAL DESCRIPTION
The ADP3301 is a member of the ADP330x family of precision
low dropout anyCAP™* voltage regulators. The ADP3301
stands out from the conventional LDOs with a novel architec-
ture, an enhanced process and a new package. Its patented
design includes a noninverting wideband driver and a stage that
permits the use of an internal “pole splitting” capacitor to
stabilize the feedback loop with a single output capacitor as
small as 0.47 µF. This device is stable with any type of capacitor
regardless of its ESR (Equivalent Serial Resistance) value,
including ceramic types (MLCC) for space restricted applica-
tions. The ADP3301 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
ADP3301 is only 100 mV (typical) at 100 mA.
In addition to the new architecture and process, ADI’s new
proprietary thermally enhanced package (Thermal Coastline)
can handle 1 W of power dissipation without external heat sink
or large copper surface on the PC board. This keeps PC board
real estate to a minimum and makes the ADP3301 very
attractive for use in portable equipment.

The ADP3301 operates with a wide input voltage range from
3 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
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)
ADP3302 (100 mA, Dual Output)
ADP3304 (100 mA, Dual Output with Separate Grounds)
ADP3303 (200 mA)
