Note 1 : Output or reference voltage temperature coefficients defined as the worst case voltage change divided by the
total temperature range.
Note 2 : Unless otherwise specified all limits guaranteed for TJ=25℃, VIN=V0+1V, IL=100㎂ and CL=1㎌. Additional condition
for the 8-pin versions are feedback tied to -XX V tap and output tied to output Sense (V OUT=XX V) and
VSHOUTDOW≤N 0.8V
Note 3 : Regulations is measured at constant junction temperature, using pulse testing with a low duty cycle.
Changes in output voltage due to heating effects are covered under the specification for thermal regulation.
