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
μ
A) 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 m
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.
