6.5 Electrical Characteristics

At operating temperature range (T_J = –40°C to +125°C),V_IN = V_OUT(NOM) + 0.5 V or 1.5 V (whichever isgreater), I_OUT = 1 mA, V_EN =V_IN, and C_IN = C_OUT = 1 uF(unless otherwise noted); all typical values are at T_J = 25°C

(1) When the device is connected to external feedback resistors at the FB pin, external resistor tolerances are not included.

(2) V_IN = 1.5 V for V_OUT < 1.0 V.

(3) V_IN = 2.0 V for V_OUT < 1.5 V.
