FEATURES

DESCRIPTION

The LT^®3022 is a very low dropout voltage (VLDO™) linear

regulator that operates from single input supplies down to

0.9V. The device supplies 1A output current with 145mV

typical dropout voltage. The LT3022 is ideal for low input

voltage to low output voltage applications, providing

comparable electrical efﬁciency to a switching regulator.

The regulator optimizes stability and transient response

with low ESR ceramic output capacitors as small as 10µF.

The LT3022 is available as an adjustable device with

an output voltage range down to the 200mV reference.

Three ﬁxed output voltages, 1.2V, 1.5V and 1.8V are also

offered. The LT3022 regulator is available in the thermally

enhanced low proﬁle (0.75mm) 16-lead (5mm × 3mm)

DFN and MSOP packages.
