Designed for a wide input voltage range of 4 to 36 V, it is capable of supplying a minimum output current of 200 m A. The output acts as a current source with a low saturation voltage; protection against shortcircuiting is provided by the device shutting down with excessive temperature. The chip is activated when the input voltage threshold V(PI)-V(NI) of typically 3.5 V is exceeded. With four leads, the input (PI, NI) and output (DN, VN) reference voltages are decoupled. The maximum permissive voltage difference between NI and VN is 36 V.
