RT9002A Datasheet | Richtek

Description The RT9002A/B/C is a dual-channel, low noise, and low dropout regulator. The first regulator is capable of sourcing 240m A, while the second regulator can source up to 500m A and includes a voltage detection function. The RT9002A/B/C performance is optimized for CD/DVD-ROM, CD/RW or wireless munication supply applications. .. The RT9002A/B/C regulator is stable with output capacitors as low as 1μF. The other features include high output accuracy, ultra-fast transient response, tight load and line regulation, current limiting/thermal protection and high ripple rejection ratio. The RT9002A/B/C is available in SOP-8 package requiring minimum board space and smallest ponents.
