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 T
A
= +25°C. Low duty pulse techniques are used during test to
maintain junction temperature as close to ambient as possible.
Note 2: Guaranteed by line regulation test.
Note 3: Not tested. For design purposes, the current limit should be considered 400mA minimum.
Note 4: The dropout voltage is defined as (V
IN
-V
OUT
) when V
OUT
is 100mV below the target value of V
OUT
. The per-
formance of every G924 part, see “Typical Performance Characteristics”.
