It is The L200 can be used to replace fixed voltage regulators when high output voltage precision is available in Pentawatt package or 4-lead TO-3 metal case. Current limiting, power limiting, thermal required and eliminates the need to stock a range shutdown and input overvoltage protection (up to of fixed voltage regulators.
