The LT3021 is a low dropout voltage linear regulator that operates from input supplies down to 0.9V. It 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 document describes the LT3021, a very low dropout voltage (VLDO) linear regulator designed to operate from input supplies down to 0.9V. It is capable of supplying up to 500mA of output current with a typical dropout voltage of 160mV and includes features such as reverse-battery protection, current limiting, and thermal limiting.
