DESCRIPTIO U
●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.
