GENERAL DESCRIPTION

ADP3333 is a member of the ADP333x family of precision low

dropout anyCAP voltage regulators. Pin-compatible with the

MAX8860, the ADP3333 operates with a wider input voltage

range of 2.6 V to 12 V and delivers a load current up to 300 mA.

ADP3333 stands out from other conventional LDOs with a

novel architecture and an enhanced process that enables it to

offer performance advantages over its competition. Its patented

design requires only a 1.0

µF output capacitor for stability. This

device is insensitive to output capacitor Equivalent Series Resis-

tance (ESR), and is stable with any good quality capacitor,

including ceramic (MLCC) types for space-restricted applica-

tions. ADP3333 achieves exceptional accuracy of

±0.8% at

room temperature and

±1.8% over temperature, line and load

variations. The dropout voltage of ADP3333 is only 140 mV

(typical) at 300 mA. This device also includes a safety current

limit, thermal overload protection and a shutdown feature. In

shutdown mode, the ground current is reduced to less than

1

µA. The ADP3333 has ultralow quiescent current, 70 µA (typ)

in light load situations.
