PIN DESCRIPTIONS

The descriptions of the pins are listed in Table 3-1.

TABLE 3-1:

PIN FUNCTION TABLE

3.1

Power and Voltage Sense Input

(PS)

PS is a dual function input that provides both feedback

voltage sensing and internal chip power. It should be

connected to the regulator output (See Section 5.0,

“Applications”).

3.2

Shutdown Input (SHDN)

A logic-low on SHDN suspends device operation and

supply current is reduced to less than 0.5 µA. The

device resumes normal operation when SHDN is again

brought high.

3.3

Inductor Switch Output (LX)

LX is the drain of an internal N-channel switching tran-

sistor. This terminal drives the external inductor, which

ultimately provides current to the load.

3.4

Ground Terminal (GND)

Connect to circuit ground.

3.5

No Connect (NC)

No internal connection.

Pin No.
