Note 1:
Absolute Maximum Ratings are limits beyond which damage can occur. Operating Ratings are conditions under which operation of the device is
guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical
Characteristics tables.
Note 2:
All Voltages are with respect to the potential at the GND pin.
Note 3:
For further information on these packages please refer to the following application notes,AN-1112 Micro SMD Wafer Level Chip Scale Package.
Note 4:
Internal thermal shutdown circuitry protects the device from permanent damage.
Note 5:
The human body model is 100pF discharged through a 1.5k
resistor into each pin. The machine model is a 200pF capacitor discharged directly into
each pin.
Note 6:
The maximum ambient temperature (T
A(max)) is dependant on the maximum operating junction temperature (TJ(max-op) = 125°C), the maximum power
dissipation of the device in the application (P
D(max)), and the junction to ambient thermal resistance of the part / package in the application (θJA), as given by the
following equation: T
A(max) = TJ(max-op) - (θJA × PD(max)).
Note 7:
Junction to ambient thermal resistance is dependant on the application and board layout. In applications where high maximum power dissipation is
possible, special care must be paid to thermal dissipation issues in board design.
Note 8:
Full details can be found in JESD61-7
Note 9:
All limits are guaranteed. All electrical characteristics having room-temperature limits are tested during production at T
J = 25°C or correlated using
Statistical Quality Control methods. Operation over the temperature specification is guaranteed by correlating the electrical characteristics to process and
temperature variations and applying statistical process control.
Note 10:
The minimum input voltage = V
OUT(NOM) + 0.5V or 1.8V, whichever is greater.
Note 11:
Dropout voltage is voltage difference between input and output at which the output voltage drops to 100mV below its nominal value. This parameter is
only specified for output voltages above 1.8V.
Note 12:
The device maintains the regulated output voltage without a load.
Note 13:
Short circuit current is measured with V
OUT pulled to 0V.
Note 14:
This electrical specification is guaranteed by design.
Note 15:
Enable Pin has an internal 3M
typical, resistor connected to GND.
Note 16:
The capacitor tolerance should be 30% or better over temperature. The full operating conditions for the application should be considered when selecting
a suitable capacitor to ensure that the minimum value of capacitance is always met. Recommended capacitor type is X7R or X5R. (See capacitor section in
Applications Hints)
