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 (VOUT=XX V) and

VSHOUTDOWN≤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.
