Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress rat-

ings 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, GND = 0V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1:Limits is 100% production tested at TA= +25°C. Limits over the operating temperature range are guar-

anteed through correlation using Statistical Quality Control (SQC) Methods.

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 150mA minimum to 420mA maximum.

Note 5:The dropout voltage is defined as (VIN - VOUT) when VOUT is 100mV below the value of VOUT for VIN = VOUT +2V.
