DESCRIPTION
The L200 is a monolithic integrated circuit for volt-
age and current programmable regulation. It is
available in Pentawatt® package or 4-lead TO-3
metal case.Current limiting, power limiting, thermal
shutdown and input overvoltage protection (up to
60 V) make the L200 virtually blow-out proof.
The L200 can be used to replace fixed voltage
regulators when high output voltage precision is
required and eliminates the need to stock a range
of fixed voltage regulators.
