RT9166B
600mA, Ultra-Fast Transient Response Linear Regulator
General Description
Features
The RT9166B is a CMOS linear regulator optimized for
ultra-fast transient response. The device is capable of
supplying up to 600mA of output current and is optimized
for CD/DVD-ROM, CD/RW or wireless communication
applications. The RT9166B regulator is stable with output
capacitor as low as 3.3μF. The other features include high
output accuracy, current limiting protection, and high ripple
rejection ratio. The RT9166B regulator is available in a
3-lead SOT-89 package.
