GENERAL DESCRIPTION

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 mΩ 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.
