1.5 AMP NEGATIVE ADJUSTABLE VOLTAGE

REGULATOR APPROVED TO DESC DRAWING 7703406

Three Terminal, Precision Adjustable

Negative Voltage Regulator In Hermetic

Style Packages (LM137A)

Please see mechanical

outlines herein

FEATURES

• Similar To Industry Standard LM137A

• Approved To DESC Standardized Military Drawing Number 7703406

• Built In Thermal Overload Protection

• Short Circuit Current Limiting

• Available In Six Package Styles

• Maximum Output Voltage Tolerance Is Guaranteed to + 1%

DESCRIPTION

These three terminal negative regulators are supplied in hermetically sealed

packages. All protective features are designed into the circuit, including thermal

shutdown, current-limiting, and safe-area control. With heat sinking, these devices

can deliver up to 1.5 amps of output current. The LCC-20 device is limited to .5

amps. The unit also features output voltages that can be fixed from -1.2 volts to -37

volts using external resistors.
