Note 1: Production tested at TA = +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 (VIN - VOUT) when VOUT equals 98% of the nominal value of VOUT when
VIN = 11V. For T/S versions, dropout voltage is defined as (VIN - VOUT) when VOUT equals 98% of the nominal value of
VOUT when VIN = 9.3V.
Note 4: Observe the absolute maximum power dissipation limits.
