DescriptionThe ADP3333 is a member of the ADP333x family of precision low dropout (LDO) anyCAP? voltage regulators. Pin compatible with the MAX8860, the product operates with a wider input voltage range of 2.6 V
ADP3333 is a member of the ADP333x family of precision low dropout 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. It 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 F 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. It achieves exceptional accuracy of ±0.8% at room temperature and ±1.8% over temperature, line and load variations. The dropout voltage of 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 A. The ADP3333 has ultralow quiescent current, 70 A (typ) in light load situations.
