RT9166-14P Overview

300/600mA, Ultra-Fast Transient Response LDO Regulator

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.
