DESCRIPTIO  
FEATURES  
The LT®3021 is a very low dropout voltage (VLDOTM) 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.  
VIN Range: 0.9V to 10V  
Dropout Voltage: 160mV Typical  
Output Current: 500mA  
Adjustable Output (VREF = VOUT(MIN) = 200mV)  
Fixed Output Voltages: 1.2V, 1.5V, 1.8V  
Stable with Low ESR, Ceramic Output Capacitors  
(3.3µF Minimum)  
0.2% Load Regulation from 0mA to 500mA  
The LT3021 regulator optimizes stability and transient  
response with low ESR, ceramic output capacitors as  
small 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.  
Quiescent Current: 120µA (Typ)  
3µA Typical Quiescent Current in Shutdown  
Current Limit Protection  
Reverse-Battery Protection  
No Reverse Current  
Internal protection circuitry includes reverse-battery pro-  
tection, current limiting, thermal limiting with hysteresis,  
andreverse-currentprotection. TheLT3021isavailableas  
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.
