The ADP3333 is a member of the ADP333x family of precision low dropout （LDO） anyCAP? voltage regulators. Pin compatible with the MAX8860， the ADP3333 operates with a wider input voltage range of 2.6 V to 12 V and delivers a load current up to 300 mA. ADP3333 stands out from other conventional LDOs with a novel architecture and an enhanced process that enables it to offer performance advantages over its competition. Its patented design requires only a 1.0 μF output capacitor for stability. This device is insensitive to output capacitor equivalent series resistance （ESR） and is stable with any good quality capacitor， including ceramic （MLCC） types for space-restricted applications. The ADP3333 achieves exceptional accuracy of ±0.8% at room temperature and ±1.8% over temperature， line， and load variations. The dropout voltage of the ADP3333 is only 140 mV （typical） at 300 mA. This device also includes a safety current limit， thermal overload protection， and a shutdown feature. In shutdown mode， the ground current is reduced to less than 1 μA. The ADP3333 has ultralow quiescent current， 70 μA （typical） in light load situations.
