GENERAL DESCRIPTION

The ADP3336 is a member of the ADP333x family of precision

low dropout anyCAP voltage regulators. The ADP3336 operates

with an input voltage range of 2.6 V to 12 V and delivers a

continuous load current up to 500 mA. The ADP3336 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

µF output capacitor for

stability. This device is insensitive to output capacitor Equiva-

lent Series Resistance (ESR), and is stable with any good

quality capacitor, including ceramic (MLCC) types for space-

restricted applications. The ADP3336 achieves exceptional

accuracy of

±0.9% at room temperature and ±1.8% over tem-

perature, line, and load. The dropout voltage of the ADP3336 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

µA. The ADP3336 has ultralow quiescent current

80

µA (typical) in light load situations.
