Preliminary
RT9166/A
300/600mA, Ultra-Fast Transient Response LDO Regulator
General Description
The RT9166/A series are CMOS low dropout regulators
optimized for ultra-fast transient response. The devices are
capable of supplying 300mA or 600mA of output current
with a dropout voltage of 230mV or 580mV respectively.
The RT9166/A series are is optimized for CD/DVD-ROM,
CD/RW or wireless communication supply applications.
The RT9166/A 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 RT9166/A regulators
are available in 3-lead SOT-23, SOT-89, SOT-223 and TO-92
packages.

Note: To prevent oscillation, a 1µF minimum X7R or X5R dielectric is strongly recommended if ceramics are
used as input/output capacitors. When using the Y5V dielectric, the minimum value of the input/output
capacitance that can be used for stable over full operating temperature range is 3.3µF. (see Application
Information Section for further details)
