Test conditions unless otherwise stated: VIN - VOUT = 5V, IOUT = 0.5A, PMAX = 20W, IMAX = 1.5A
Regulation is measured at constant junction temperature, using pulse testing at a low duty cycle. Changes in output voltage due to heating
effects are covered under thermal regulation specifications. Load regulation is measured at
