The LT3022 is a very low dropout voltage (VLDOTM) linear regulator that operates from single input supplies down to 0.9V. The device supplies 1A output current with 145mV typical dropout voltage. The LT3022 is ideal for low input voltage to low output voltage applications, providing comparable electrical efficiency to a switching regulator. The regulator optimizes stability and transient response with low ESR ceramic output capacitors as small as 10F Other LT3022 features include 0.05% typical line .
