ADP3338AKC-1.5

Product Summary

The ADP3338AKC-1.5 is a member of the ADP33xx family of precision low dropout anyCAP voltage regulators. The ADP3338AKC-1.5 operates with an input voltage range of 2.7 V to 8 V and delivers a load current up to 1 A. The ADP3338AKC-1.5 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 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 ADP3338AKC-1.5 achieves exceptional accuracy of ±0.8% at room temperature and ±1.4% over temperature, line and load variations. The dropout voltage of the ADP3338AKC-1.5 is only 190 mV (typical) at 1 A. This device also includes a safety current limit and thermal overload protection. The ADP3338AKC-1.5 has ultralow quiescent current 110 μA (typical) in light load situations.
