GENERAL DESCRIPTION
The ADP3335 is a member of the ADP330x family of precision
low dropout anyCAP voltage regulators. The ADP3335 operates
with an input voltage range of 2.6 V to 12 V and delivers a con-
tinuous load current up to 500 mA. The ADP3335 stands out
from conventional LDOs with the lowest thermal resistance of
any MSOP-8 package and an enhanced process that enables it
to offer performance advantages beyond its competition. Its
patented design requires only a 1.0
μ
F output capacitor for sta-
bility. This device is insensitive to output capacitor Equivalent
Series Resistance (ESR), and is stable with any good quality
capacitor, including ceramic (MLCC) types for space-restricted
applications. The ADP3335 achieves exceptional accuracy of
±
0.9% at room temperature and
±
1.8% over temperature, line,
and load. The dropout voltage of the ADP3335 is only 200 mV
(typical) at 500 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
μ
A. The ADP3335 has ultralow quiescent current 80
μ
A
(typical) in light load situations.
