OPERATING CONDITIONS
Operating conditions are conditions under which operation of the device is intended to be functional. All values are
referenced to GND.
MIN and MAX limits are valid for the recommended ambient temperature range of -40°C to 85°C. Typical values represents
statistically the utmost probability at following conditions: V
IN
= 3.3V, V
OUT
= 1.8V, I
OUT
= 4A, C
IN1
= 47µF ceramic,
C
IN2
= 220µF polymer electrolytic, C
OUT1
= 47µF ceramic, C
OUT2
= 100µF poly-tantalum unless otherwise noted.
