ADP3310中文资料亚德诺数据手册PDF规格书

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.
