ADP3330:  High Accuracy Ultralow I(Q), 200 mA, SOT-23, anyCAP® Low Dropout Regulator

Product Details

The ADP3330 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3330 operates with an input voltage range of +2.9 V to +12 V and delivers a load current up to 200 mA. The ADP3330 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 0.47 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 ADP3330 achieves exceptional accuracy of ±0.7% at room temperature and ±1.4% over temperature, line and load variations. The dropout voltage of the ADP3330 is only 140 mV (typical) at 200 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 2 µA. The ADP3330 has ultralow quiescent current 34 µA (typ) in light load situations.
