Note 3: stable state with fixed IOUT condition

Note 4: VOUT = 2.5 V

Note 5: except Control pull down current (ICT)

Note 6: tr = tf = 1.0 μs (Defined when 10 % to 90 % is 0.8 µs)

Note 7: Pulse measurement

Note 8: This parameter is warranted by design.

Note 9: VDO = VIN1 - (VOUT1 x 0.97)

VOUT1 is the output voltage when VIN = VOUT + 1.0 V.

VIN1 is the input voltage at which the output voltage becomes 97 % of VOUT1 after gradually

decreasing the input voltage.
