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 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.
