The ADP3342 is a unique member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3342 operates with an input voltage range of 1.7 V to 6 V and delivers a continuous load current up to 300 mA. In order to support the ability to regulate from such a low input voltage, the power rail to the IC, VCC, has been split off from the main power rail, VIN, from which the output is powered. The ADP3342 stands out from the conventional LDOs with the lowest thermal resistance of any MSOP-8 package and an enhanced process that enables it to offer performance advantages beyond its competition. Its patented design requires only a 1.0 F 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 spacerestricted applications. The dropout voltage of the ADP3342 is only 190 mV (typical) at 300 mA. This device also includes a safety current limit, thermal overload protection and a shutdown control pin.
