Description
AI
The LT3022 is a very low dropout voltage (VLDO™) 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 10μF. Other LT3022 features include 0.05% typical line regulation and 0.05% typical load regulation. In shutdown, quiescent current typically drops to 7.5μA. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting with hysteresis and reverse-current protection.The LT3022 is available as an adjustable device with an output voltage range down to the 200mV reference. Three fixed output voltages, 1.2V, 1.5V and 1.8V are also offered. The LT3022 regulator is available in the thermally enhanced low profile (0.75mm) 16-lead (5mm × 3mm) DFN and MSOP packages.ApplicationsHigh Efficiency Linear RegulatorsBattery-Powered SystemsLogic SuppliesPost Regulator for Switching SuppliesWireless ModemsFPGA Core Supplies
