(1) Unless otherwise noted, the following test conditions apply: |V_I – V_O| = 5 V and I_OMAX = 1.5 A, T_J = 0°C to 125°C. Pulse testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible.

(2) Line regulation is expressed here as the percentage change in output voltage per 1-V change at the input.

(3) Maximum power dissipation is a function of T_J(max), θ_JA, and T_A. The maximum allowable power dissipation at any allowable ambient temperature is P_D = (T_J(max) – T_A) / θ_JA. Operating at the absolute maximum T_J of 150°C can affect reliability.

(4) C_ADJ is connected between the ADJUST terminal and GND.
