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 metalcase.Current limiting, powerlimiting, thermal shutdown and input overvoltage protection (up to January 2000 Pentawatt TO-3 (4 lead) 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.
