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

metal case. Current limiting, power limiting, thermal

shutdown and input overvoltage protection (up to

January 2000

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.

L200 Figure 23. Programmable Voltage and Current Regulator. 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).

L200 Figure 26. High Input and Output Voltage. Figure 27. Constant Current Battery Charger. The resistors R1 and R2 determine the final charging voltage and R SC 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.
