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.

Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. Devices are ESD sensitive. Handling precaution recommended.
Note 3. The device is not guaranteed to function outside its operating conditions.
Note 4. θJA is measured in the natural convection at TA = 25°C on a high effective thermal conductivity test board of JEDEC
51-7 2S2P 4-layer thermal measurement standard.
Note 5. Regulation is measured at constant junction temperature by using a 20ms current pulse. Devices are tested for load
www.DataSheet4U.coremgulation in the load range from 1mA to 100mA.
Note 6. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV.
Note 7. Quiescent, or ground current, is the difference between input and output currents. It is defined by IQ = IIN - IOUT under no
load condition (IOUT = 0mA). The total current drawn from the supply is the sum of the load current plus the ground pin
current.
