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.
