RT9001
600mA, Ultra-Fast Transient Response LDO Regulator
General Description
The RT9001 series are CMOS low dropout regulators
optimized for ultra-fast transient response. The devices are
capable of
supplying 600mA of output current with a dropout
voltage of 580mV respectively.
The RT9001 series are is optimized for CD/DVD-ROM,
CD/RW or wireless communication supply applications.
The RT9001 regulators are stable with output capacitors
as low as 1μF. The other features include ultra low dropout
voltage, high output accuracy, current limiting protection,
and high ripple rejection ratio.
The devices are available in fixed output voltages range of
1.2V to 4.5V with 0.1V per step. The RT9001 regulators
are available in 3-lead SOT-223 package.
