RT9002A

Dual Low Dropout Regulator with Detector

Richtek Technology 

RT9002A/B/C

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. 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 3. Devices are ESD sensitive. Handling precaution recommended.

Note 4. The device is not guaranteed to function outside its operating conditions.

Note 5. Regulation is measured at constant junction temperature by using a 20ms current pulse. Devices are tested for load

regulation 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.
