Not connected.

Power and voltage sense input. This dual function input provides both feedback voltage sensing

and internal chip power. It should be connected to the regulator output. (See Section 4.0,

Applications).

Shutdown input. A logic low on this input suspends device operation and supply current is

reduced to less than 0.5µA. The device resumes normal operation when SHDN is again brought

high.

Inductor switch output. LX is the drain of an internal N-channel switching transistor. This terminal

drives the external inductor, which ultimately provides current to the load.

Ground terminal.
