Linear Regulator  
FEATURES  
DESCRIPTION  
The LT®3021 is a very low dropout voltage (VLDO™) lin-  
ear 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  
responsewithlowESR,ceramicoutputcapacitorsassmall  
as 3.3μF. Other LT3021 features include 0.05% typical line  
regulation and 0.2% typical load regulation. In shutdown,  
quiescent current typically drops to 3μA.  
Reverse-Battery Protection  
No Reverse Current  
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.
