3A Fixed Output Voltage LDO Regulator
General Description
The RT9172 series of low-dropout linear regulators
operate from a +2.25V to +6.0V input supply. A wide
range of preset output voltage options is available.
These low dropout linear regulators respond very
fast to step changes in load, which are suitable for
low voltage microprocessor applications. The
RT9172 uses an internal PMOS as the pass device,
which does not cause extra GND current in heavy
load and dropout condition. The shutdown mode of
low operation current makes the IC suitable for
power-saving systems. The other features include
current limiting and over temperature protection.
