The LT®3022 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.
