OBSOLETE PRODUCT — ADP3310:  Precision Voltage Regulator Controller

The ADP3310 is a precision voltage regulator controller that can be used with an external Power PMOS device such as the NDP6020P to form a two chip low dropout linear regulator. The low quiescent current (800 µA) and the Enable feature make this device especially suitable for battery powered systems. The dropout voltage at 1 A is only 70 mV when used with the NDP6020P, allowing operation with minimal headroom and prolonging battery useful life. The ADP3310 can drive a wide range 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 to protect the external MOSFET and foldback current limit. A current limit threshold voltage of 50 mV (typ) allows 50 mW of board metal trace resistance to provide a 1 A current limit. The ADP3310 operates from a wide input voltage range from 2.5 V to 15 V and is available in a small SO-8 package.
