Note 1: A load step of 2 A can be applied provited that input-output differential voltage is lower than 20 V (see Figure 3). Note 2: The same performance can be maintained at higher output levels if a bypassing capacitor is provited between pins 2 and 4.

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).

Figure 26. High Input and Output Voltage. Figure 27. Constant Current Battery Charger.
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.
