Triple, Ultra-Fast CMOS LDO Regulator

Richtek Technology 

RT9185

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. 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 1.5A, 0.8A and 0.3A for each LDO respectively.

Note 5. 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.

Note 6. θJA is measured in the natural convection at TA = 25°C on a low effective thermal conductivity test board of

JEDEC 51-3 thermal measurement standard. The pad size is 100mm2 on TO-252 packages, 125mm2 on TO-263

packages.
