Dual LDO Regulator with Reset Function
General Description
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 1
μ
F, 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.
The RT9006A/B regulators are available in used
SOP-8
(Exposed Pad) surface mount package.
