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 -47
volts using external resistors.
