designed to provide 2A with high efficiency using simple
3-terminal configurations. All internal circuitry is
designed to operate down to 1V input-to-output
differential and the dropout voltage is fully specified as a
function of load current. Dropout is guaranteed at a
maximum of 1.5V at maximum output current, decreasing
at lower load currents. Available in fixed voltages.
Current limit is trimmed to ensure specified output current
and controlled short-circuit current. On-chip thermal
limiting provides protection against any combination of
overload that would create excessive junction
temperatures.

Notes:
1) See thermal regulation specification for changes in output voltage due to heating effects. Load and line regulation are measured at a constant
junction temperature by low duty cycle pulse testing.
2) Line and load regulation is guaranteed up to the maximum power dissipation in the package. Input/output differential and the output current
determine power dissipation. Guaranteed maximum output power will not be available over the full / input/output voltage range.
3) IFull Load is defined as the maximum value of output load current as a function of the input-to-output voltage. IFull Load is equal to 2.0 Amps.
