These three terminal negative voltage 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 unit also
features output voltages that can be fixed from -1.2
volts to -37 volts using external resistors.
Features:
n Similar to Industry Standard LM137A
n Approved to DSCC Standardized Military
Drawing Number 7703406
n Built-in Thermal Overload Protection
n Short Circuit Current Limiting
n Maximum Output Voltage Tolerence is
Guaranteed ±1%
n This part is also available in
TO-257AA Package as OM1325ST(Isolated),
TO-257AA Package as OM1325NT(Non-Isolated),
SMD-1 Package as OM1325NM,
TO-204 Package as OM1325NK

Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used.
Changes in output voltage due to heating effects must be taken into account separately.
If not tested, shall be guaranteed to the specified limits.
