Three Terminal, Adjustable Voltage, 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.

Notes:

1.Unless otherwise specified, these specifications apply for (VIN - VOUT) = 5.0V and IOUT = 1.5A.

2.Regulation is measured at a constant junction temperature using a pulse technique. Changes in output voltage due to heating effects are covered under the specification for thermal regulation.

3.Guaranteed if not tested to the limits specified.
