(1) I_MAX = 1.5 A for the NDE (TO-220). I_MAX = 1.0 A for the DCY (SOT-223) package.
I_MAX = 0.5 A for the NDT (TO) and NDP (TO-252) packages. Device power dissipation (P_D) is limited by ambient temperature (T_A), device maximum junction temperature (T_J), and package thermal resistance (θ_JA). The maximum allowable power dissipation at any temperature is : P_D(MAX) = ((T_J(MAX) – T_A) / θ_JA). All minimum and maximum 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.
