IMAX = 1.0A for the DCY (SOT-223) package. IMAX = 0.5A for the NDT (TO), MDT (PFM), and NAJ (LCCC) packages. Device power dissipation (PD) is limited by ambient temperature (TA), device maximum junction temperature (TJ), and package thermal resistance (θJA). The maximum allowable power dissipation at any temperature is : PD(MAX) = ((TJ(MAX) - TA)/θJA). All Min. and Max. limits are ensured to TI's Average Outgoing Quality Level (AOQL). (2) Regulation is measured at a constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are covered under the specifications for thermal regulation.
