The RT9184A is a dual-channel LDO regulator from richtek with low quiescent current, low dropout voltage, high accuracy, large current and other features. It is suitable for CD/DVD-ROM, CD/RW, wireless LAN card/keyboard/mouse, battery-powered equipment, XDSL router and other applications.
The RT9184A series is an efficient, precise dual-channel CMOS LDO regulator designed for applications such as CD/DVD-ROM drives and wireless communication supplies. It features two independent regulator outputs capable of sourcing up to 500mA each, with performance optimized for stability using output capacitors as low as 1µF.
Key characteristics include ultra-low quiescent current (typically 440µA), a wide operating voltage range from 2.8V to 5.5V, and an ultra-fast transient response. The device incorporates protection features such as current limiting, thermal shutdown, and is available in a fused SOP-8 package.
| Output Current | 500mA per channel |
|---|---|
| Quiescent Current | 440µA (Typ) |
| Dropout Voltage | 600mV at 500mA |
| Operating Voltage Range | 2.8V to 5.5V |
