Note 1: Production tested at T_A = +25°C. Overtemperature limits are guaranteed by design.
Note 2: Device tested at internally set voltage.
Note 3: Dropout voltage for L/M versions is defined as (V_IN - V_OUT) when V_OUT equals 98% of the nominal value of V_OUT when
V_IN = 11V. For T/S versions, dropout voltage is defined as (V_IN - V_OUT) when V_OUT equals 98% of the nominal value of V_OUT
when V_IN = 9.3V.
Note 4: Observe the absolute maximum power dissipation limits.
