Stresses beyond those listed under "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 for extended periods may affect device reliability.

Note 1: Limits is 100% production tested at TA= +25°C. Low duty pulse techniques are used during test to

maintain junction temperature as close to ambient as possible.

Note 2: VIN (min)=VOUT (STD)+VDROPOUT

Note 3: Not tested. For design purposes, the current limit should be considered 400mA minimum to 600mA maximum.

Note 4: The dropout voltage is defined as (VIN - VOUT) when VOUT is 100mV below the value of VOUT for VIN = VOUT +1V. The

performance of every G914X version, see “Typical Performance Characteristics”.

Note 5: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for

load regulation in the load range from 1mA to 300mA. Changes in output due to heating effects are covered by the

thermal regulation specification.
