DESCRIPTION

The L200 is a monolithic integratedcircuit for volt­age and current programmable regulation. It is
available in Pentawatt

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 voltageregulators.

Note: Connecting point A to a negative voltage (for example - 3V/10 mA) it is possibleto extend the output voltage

range down to 0 V and obtainthe current limiting down to this level(output short-circuit condition).
