DESCRIPTION
This three terminal positive adjustable voltage regulator is designed to provide 7.5A
with higher efficiency than conventional voltage regulators. This device is designed
to operate down to 1 volt input to output differential and the dropout voltage is fully
specified as a function of load current. Supplied in easy-to-use hermetic TO-258
package, this device is ideally suited for Military applications where small size and
high reliability is required.

Notes:
1. Line and Load Regulation are measured at a constant junction temperature using a low duty cycle pulse technique.
Although power dissipation is internally limited, regulation is guaranteed up to the maximum power dissipation of 60 W.
Power dissipation is determined by the input/output differential voltage and the output current. Guaranteed maximum
power dissipation will not be available over the full input/output voltage range.
2. Guaranteed by design, characterization or correlation to other tested parameters.
3. The • denotes the specifications which apply over the full operating temperature range.
