5 AMP LOW DROPOUT POSITIVE ADJUSTABLE

REGULATOR APPROVED TO DESC DRAWING 5962-89521

Three Terminal, Positive Adjustable

Low Dropout Voltage Regulator In

Hermetic Packages

FEATURES

• Similar To Industry Standard LT1084

• Approved To DESC Standardized Military Drawing Number 5962-89521

• Adjustable Output Voltage

• Built In Thermal Overload Protection

• Short Circuit Current Limiting

• Maximum Output Voltage Tolerance is Guaranteed To 1ꢀ

• Guaranteed Dropout Voltage At Multiple Current Levels

• TO-258 Available in Isolated and Non-Isolated Packages

DESCRIPTION

This three terminal positive adjustable voltage regulator is designed to provide 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 and

TO-3 packages, 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 45 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.
