RT9184/RT9184A pdf datasheet (

The RT9184A series are an efficient, precise dual-channel
CMOS LDO regulator optimized for ultra-low-quiescent
applications. Both regulator outputs are capable of sourcing
500mA of output current.
The RT9184A's performance is optimized for CD/DVD-ROM,
CD/RW or wireless communication supply applications.
The RT9184A 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 RT9184A regulators are available in fused SOP-8
package. Key features include current limit, thermal
shutdown, fast transient response, low dropout voltage,
high output accuracy, current limiting protection, and high
ripple rejection ratio.
