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 voltage and current programmable regulation. It is available in Pentawatt package or 4-lead TO-3 metal case.Current limiting, power limiting, thermal shutdown and input overvoltage protection (up to 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.

Note: Connecting point A to a negative voltage (for example - 3V/10 mA) it is possible to extend the output voltage range down to 0 V and obtain the current limiting down to this level (output short-circuit condition).

The resistors R1 and R2 determine the final charging voltage and RSC the initial charging current. D1 prevents discharge of the battery throught the regulator. The resistor RL limits the reverse currents through ther regulator (which should be 100 mA max) when the battery is accidentally reverse connected. If RL is in series with a bulb of 12 V/50 mA rating this will indicate incorrect connection. Figure 28. 30 W Motor Speed Control. Figure 29. Loww Turn on. Figure 30. Light Controller. 9/12 L200 DIM.
