RT9006A/B
Dual LDO Regulator with Reset Function
General Description
Features
The RT9006A/B is an efficient, precise dual-channel CMOS
LDO regulator optimized for ultra-low-quiescent
applications. Regulators output1 and output2 are capable
of sourcing 300mA and 500mA of output current.
The RT9006’ s performance is optimized for CD/DVD-ROM
and CD/RW a supply applications.
The RT9006A/B regulators are stable with output capacitors
as low as 1μF, including current limit, thermal shutdown
protection, fast transient response, low dropout voltage,
high output accuracy, current limiting protection, and high
ripple rejection ratio. The RT9006A/B contains a reset
circuit to detect VOUT2 voltage.
