产品名称：进口原装RT9166-50PXL

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, TO-92 and TO-252 packages.

Note :
Richtek products are :
► RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020.
► Suitable for use in SnPb or Pb-free soldering processes.

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.
