Adjustable, 300mA LDO Regulator with Enable

Richtek Technology 

RT9179

Note 1. Stresses listed as the abovez "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. The dropout voltage is defined as VIN -VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV.

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. Standby current is the input current drawn by a regulator when the output voltage is disabled by a shutdown signal

(VEN ≤ 0.4V). It is measured with VIN = 5.5V.

Note 7. 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.
