Dual Low Dropout Regulator with Detector

Ordering Information

General Description

The RT9002A/B/C is a dual-channel, low noise, and low

dropout regulator. The first regulator is capable of sourcing

240mA, while the second regulator can source up to

500mA and includes a voltage detection function. The

RT9002A/B/C performance is optimized for CD/DVD-ROM,

CD/RW or wireless communication supply applications.

The RT9002A/B/C regulator is stable with output capacitors

as low as 1

μF. 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 components.
