PROTECTION THERMAL OVERLOAD PROTECTION LOW BIAS CURRENT ON REGULATION PIN Pentawatt® TO-3 (4 lead) LOW STANDBY CURRENT DRAIN DESCRIPTION The L200 is a monolithic integrated circuit for volt- 60 V) make the L200 virtually blow-out proof. age and current programmable regulation. It is The L200 can be used to replace fixed voltage available in Pentawatt® package or 4-lead TO-3 regulators when high output voltage precision is 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.
