6.6 Electrical Characteristics
Unless otherwise specified: V_IN = 5 V, V_SHDN = 5 V, I_L = 0 mA, and T_J = 25°C. Minimum and Maximum limits are ensured
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.
