Specifications with standard type are for an Operating Junction Temperature of T_J = 25^°C only; limits applying over the full Operating Junction Temperature range are denoted by a "•". Minimum and Maximum limits are guaranteed through test, design, or statistical correlation. Typical values represent the most likely parametric norm at T_J = 25^°C , and are provided for reference purposes only. Unless otherwise indicated, V_IN = V_OUT + 1V ( V_IN = V_OUT + 1.2V for 1.2V option), I_L = 100μA , C_L = 1μF , V_EN ≥ 2.5V , T_A = T_J = 25^°C .
