ADP3308ART-2.5中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The ADP3308 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. It is pin-for-pin and functionally compatible with National’s LP2980, but offers performance advantages. The ADP3308 stands out from the conventional LDOs with a novel architecture and an enhanced process. Its patented design requires only a 0.47 µF output capacitor for stability. This device is stable with any type of capacitor regardless of its ESR (Equivalent Serial Resistance) value, including ceramic types for space restricted applications.
