描述 Description

The ADP3310 is a precision voltage regulator controller thatcan be used with an external Power PMOS device such as theNDP6020P to form a two chip low dropout linear regulator.The low quiescent current (800 µA) and the Enable featuremake this device especially suitable for battery powered systems.The dropout voltage at 1 A is only 70 mV when used with theNDP6020P, allowing operation with minimal headroom andprolonging battery useful life. The ADP3310 can drive a widerange of currents, depending on the external PMOS device used. Additional features of this device include: high accuracy (±1.5%)over line, load and temperature, gate-to-source voltage clamp toprotect the external MOSFET and foldback current limit. Acurrent limit threshold voltage of 50 mV (typ) allows 50 mW ofboard metal trace resistance to provide a 1 A current limit.The ADP3310 operates from a wide input voltage range from2.5 V to 15 V and is available in a small SO-8 package.
