GENERAL DESCRIPTION

The ADP3303 is a member of the ADP330x family of precision

low dropout anyCAP¹voltage regulators. The ADP3303 stands

out from the conventional LDOs with a different architecture,

an enhanced process, and a different package. Its patented design

requires only a 0.47 µF output capacitor for stability. This device

is insensitive to capacitor Equivalent Series Resistance (ESR)

and is stable with any good quality capacitor, including ceramic

types (MLCC) for space restricted applications. The ADP3303

achieves exceptional accuracy of 0.8% at room temperature

and 1.4% overall accuracy over temperature, line, and load

regulations. The dropout voltage of the ADP3303 is only

180 mV (typical) at 200 mA.

The ADP3303 operates with a wide input voltage range from

3.2 V to 12 V and delivers a load current in excess of 200 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:

In addition to the architecture and process, the Analog Devices,

Inc., proprietary thermally enhanced package (Thermal Coastline)

can handle 1 W of power dissipation without external heatsink

or large copper surface on the printed circuit board (PCB). This

keeps PCB real estate to a minimum and makes the ADP3303

very attractive for use in portable equipment.
