Description

These OM1325NMM 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 OM1325NMM also features output voltages that can be fixed from -1.2 volts to -37 volts using external resistors.
