L200 ADJUSTABLE VOLTAGE AND CURRENT REGULATOR ADJUSTABLE OUTPUT CURRENT UP TO 2 A (GUARANTEED UP TO Tj = 150 °C) ADJUSTABLE OUTPUT VOLTAGE DOWN TO 2.85 V INPUT OVERVOLTAGE PROTECTION (UP TO 60 V, 10 ms) SHORT CIRCUIT PROTECTION OUTPUT TRANSISTOR S.O.A.PROTECTION THERMAL OVERLOAD PROTECTION LOW BIAS CURRENT ON REGULATION PIN LOW STANDBY CURRENT DRAIN 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, power limiting, thermal shutdown and input overvoltage protection (up to March 1993 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.
