RT9002A/B/C
Dual Low-Dropout Regulator with Detector
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,
www.DataSCheDet/4RUW.coomr wireless communication 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 components.
