ORDERING CODES

ELECTRICAL CHARACTERISTICS (CI =1µF, CO =1µF (tantalium connected between OUT pin and

GND pin) or CCMP =1µF (ceramic X7R connected between CMP pin and GND pin) (unless otherwise

specified)

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 VOUT 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 TJ =95°C, TA=85°C and RTJA=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 TA=85°C, and it must be derated by 4.5mW for each degree above 85°C
