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.

Applications

  • CD/DVD-ROM, CD/RW
  • Wireless LAN Card/Keyboard/Mouse
  • Battery-Powered Equipment
  • XDSL Router
