DESCRIPTION
This three terminal negative regulator is supplied in a hermetically sealed surface
mount package. All protective features are designed into the circuit, including thermal
shutdown, current limiting and safe-area control. With heat sinking, they can deliver
over 1.0 amp of output current. This unit features output voltages that can be
trimmed using external resistors, from -1.2 volts to -47 volts.
