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. Electrical Characteristics (VIN =+3.6V, V SHDN =VIN, TA =TJ =+25°C, unless otherwise noted.)

Low duty pulse techniques are used during test to maintain junc- tion temperature as close to ambient as possible. Note 2: Guaranteed by line regulation test. Note 3: Adjustable mode only. Note 4: Not tested. For design purposes, the current limit should be considered 400mA minimum to 650mA maximum. Note 5: The dropout voltage is defined as (VIN-VOUT) when VOUT is 100mV below the target value of VOUT. The performance of every G923 part, see “Typical Performance Characteristics”. |
