Hot-selling and scarce ADP3331ARTZ-REEL7 Adjustable Output Low Dropout Regulator SOT23-6 spot stock

Product Descriptions

The ADP3331 is a member of the ADP330x family of precisionlow dropout anyCAP voltage regulators . The ADP3331 operateswith an input voltage range of 2.6 V to 12 V and delivers a loadcurrent up to 200 mA . The ADP3331 stands out from theconventional LDOs with a novel architecture and an enhancedprocess that enables it to offer performance advantages and higheroutput current than its competition . Its patented design requiresonly a 0.47 mF output capacitor for stability .This device is insensitive to capacitor equivalent series resistance (ESR), and is stablewith any good quality capacitor, including ceramic (MLCC) types ​for space restricted applications . The ADP3331 achieves exceptional accuracy of ±0.7% at room temperature and ±1.4% overallaccuracy over temperature, line, and load variations . The dropout voltage of the ADP3331 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, theground current is reduced to less than 2 mA . The ADP3331 hasultralow quiescent current 34 mA (typical) in light load situations .The SOT-23-6 package has been thermally enhanced usingAnalog Device’s proprietary Chip-on-Lead feature to maximize power dissipation .
