f = 1kHz, VIN = VOUT + 1V,

COUT = 2.2μF, ILOAD = 50mA

f = 10kHz, VIN = VOUT + 1V,

COUT = 2.2μF, ILOAD = 50mA

f = 100kHz, VIN =VOUT + 1V,

COUT = 2.2μF, ILOAD = 50mA

f = 200kHz, VIN = VOUT + 1V,

Note 1. Stresses beyond those listed “Absolute Maximum Ratings” may cause permanent damage to the device. These are

stress ratings only, and 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 may

affect device reliability.

Note 2. θJA is measured at TA = 25°C on a high effective thermal conductivity four-layer test board per JEDEC 51-7. The CSP

balls connect directly to the internal GND copper plane by 2 vias, the via diameter is about 1mm.

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

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

Note 5. The dropout voltage is defined as VIN − VOUT, which is measured when VOUT is VOUT(NORMAL) − 100mV.

Note 6. It is guaranteed by design.
