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.
