3.0 AMP POSITIVE ADJUSTABLE VOLTAGE REGULA TOR
APPROVED TO DESC DRAWING 5962-87675

Three T erminal, Adjustable V oltage, 3.0 Amp
Precision Positive Regulator In Hermetic
JEDEC TO-257AA Package

FEATURES

• Approved To DESC Standardized Military Drawing
5962-8767501UX/TX and 5962-8767502UX/TX

• Isolated Hermetic Package, JEDEC TO-257AA Outline

• Reference Voltages Set To ±1% and ±2%

• Built-In Thermal Overload Protection

• Short Circuit Current Limiting

• Similar Electrically To Industry Standard LM150A

DESCRIPTION

These three terminal positive regulators approved by DESC, are supplied in
a hermetically sealed isolated, metal TO-257 package. All protective features
are designed into the circuit including thermal shutdown, current limiting and safe­area control. With heat sinking, they can deliver over 3.0 amps of output current.
These units feature 1% and 2% initial voltage tolerance, 0.35% load regulation and
.01% line regulation.
