6.5 Electrical Characteristics

over operating temperature range (T_J = –40°C to 125°C), V_IN = V_OUT(TYP) + 0.3 V or 2.7 V, whichever is greater; I_OUT = 1 mA, V_EN = V_IN, C_OUT = 2.2 μF, and C_NR = 0.01 μF (unless otherwise noted); for TPS79901-Q1, V_OUT = 3 V; typical values are at T_J = 25°C

(1) Minimum V_IN = V_OUT + V_DO or 2.7 V, whichever is greater.

(2) V_DO is not measured for devices with V_OUT(NOM) < 2.8 V because minimum V_IN = 2.7 V.
