Note 1:Time for the output Voltage to rise from 50% to 85% of nominal value.
Note 2: Time for the output Voltage to fall from 85% to 50 of nominal value.
Note 3: Regulator must be able to sustain Regulated Output Voltage without load.
Note 4: Parameters are uncritical as long as the output voltage stays within limits.
Note 5: A sudden voltage rise/drop of 500mV mustn't bring the output Voltage out of limits.
Note 6: Ceramic Capacitors can be used if connected between CMP pin and GNG, instead of V_OUT pin and GND.
Note 8: Maximum and minimum values are guaranteed in full temperature range.
Note 9: Line transient is tested when the input voltage changes from 2.7 to 3.2V in 10µs in full load range.
Note 10: Line transient is tested when the input voltage changes from 3.2 to 2.7V in 10µs in full load range.
Note 11: Load transient is tested when the load changes from 0.1 to 15mA in 10µs in all the input range
Note 13: Response time is defined as the time form the load line step until the output reaches a value within specification (1.41V, 1.59V).
Note 14: The maximum power dissipation for the operation depends on the ambient temperature.
For T_J =95°C, T_A=85°C and R_TJA=220°C/W the maximum power can be 0.045W. The maximum power dissipation for operation can be
increased by 4.5mW each degree below T_A=85°C, and it must be derated by 4.5mW for each degree above 85°C
