ADM7172: 6.5 V, 2 A, Ultralow Noise, High PSRR, Fast Transient Response CMOS LDO
The ADP3339 is a member of the ADP33xx family of precision low dropout anyCAP® voltage regulators. The ADP3339 operates with an input voltage range of 2.8 V to 6 V and delivers a load current up to 1.5 A. The ADP3339 stands out from the conventional LDOs with a novel architecture and an enhanced process that enables it to offer performance advantages and higher output current than 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 ADP3339 achieves exceptional accuracy of 0.9% at room temperature and 1.5% over temperature, line and load variations. The dropout voltage of the ADP3339 is only 230 mV (typical) at 1.5 A. This device also includes a safety current limit and thermal overload protection. The ADP3339 has ultralow quiescent current 130 uA (typical) in light load situations.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
