The LT
3021 is a very low dropout voltage (VLDO
TM
) linear
regulator that operates from input supplies down to 0.9V.
This device supplies 500mA of output current with a
typical dropout voltage of 160mV. The LT3021 is ideal for
low input voltage to low output voltage applications,
providing comparable electrical efficiency to that of a
switching regulator.
The LT3021 regulator optimizes stability and transient
response with low ESR, ceramic output capacitors as
small as 3.3
μ
F. Other LT3021 features include 0.05%
typical line regulation and 0.2% typical load regulation. In
shutdown, quiescent current typically drops to 3
μ
A.
Internal protection circuitry includes reverse-battery pro-
tection, current limiting, thermal limiting with hysteresis,
and reverse-current protection. The LT3021 is available as
an adjustable output device with an output range down to
the 200mV reference. Three fixed output voltages, 1.2V,
1.5V and 1.8V, are also available.
The LT3021 regulator is available in the low profile
(0.75mm) 16-pin (5mm
×
5mm) DFN package with ex-
posed pad and the 8-lead SO package.
