GENERAL DESCRIPTION

The ADP3306 is a member of the ADP330x family of precision

TECHNICAL

DATA

GND

low dropout anyCAP™ voltage regulators. The ADP3306

stands out from the conventional LDOs with a novel architec-

ture, an enhanced process and a new package. Its patented

design requires only a 0.1 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 applications. The ADP3306

achieves exceptional accuracy of ±1.0% at room temperature and

±1.5% overall accuracy over temperature, line and load regula-

tions. The dropout voltage of the ADP3306 is only 300 mV

(typical) at 300 mA.

Figure 1. Typical Application Circuit

The ADP3306 operates with a wide input voltage range from

3.2 V to 12 V and delivers a load current in excess of 300 mA. It

features an error flag that signals when the device is about to lose

regulation or when the short circuit or thermal overload protec-

tion is activated. Other features include shutdown and optional

noise reduction capabilities. The ADP330x anyCAP™ LDO fam-

ily offers a wide range of output voltages and output current

levels from 50 mA to 300 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 ADP3306 very attrac-

tive for use in portable equipment.
