OM1322SMM OM1322NMM OM1322NKM OM1322NTM OM1322STM OM1322N2M 1.5 AMP NEGATIVE ADJUSTABLE VOLTAGE REGULATOR APPROVED TO DESC DRAWING 7703403 Three Terminal, Precision Adjustable Negative Voltage Regulator In Hermetic Style Packages (LM137) Please see mechanical outlines herein FEATURES • • • • • Similar To Industry Standard LM137 Approved To DESC Standardized Military Drawing Number 7703403 Built In Thermal Overload Protection Short Circuit Current Limiting Available In Six Package Styles 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.
