Product Details

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 architecture, 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 applications. The ADP3301 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 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 200 mA:

ADP3300 (50 mA, SOT-23)
ADP3303 (200 mA)
