ADI ADP3334ACP-REEL7

The ADP3334 is a member of the ADP333x family of precision low dropout anyCAP voltage regulators. The ADP3334 operates with an input voltage range of 2.6 V to 11 V and delivers a continuous load current up to 500 mA. The novel anyCAP architecture requires only a very small 1 μF output capacitor for stability, and the LDO is insensitive to the capacitor’s equivalent series resistance (ESR). This makes the ADP3334 stable with any capacitor, including ceramic (MLCC) types for space restricted applications. The ADP3334 achieves exceptional accuracy of ±0.9% at room temperature and ±1.8% over temperature, line, and load. The dropout voltage of the ADP3334 is only 200 mV (typical) at 500 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 μA. The ADP3334 has low quiescent current of 90 μA (typical) in light load situations. The ADP3334 is available in three different package options: 1. Excellent thermal capability, space saving 3 mm×3 mm LFCSP. 2. Popular low profile MSOP - 8. 3. Traditional thermal enhanced SOIC - 8.
