Symbol
Description
1
—
SHDN
Shutdown input. A logic low on this input suspends device opera-
tion and supply current is reduced to less than 0.5
μA. The device
resumes normal operation when SHDN is again brought high.
—
1
SENSE
Voltage sense input. This input provides feedback voltage sensing
to the internal error amplifier. It must be connected to the output
voltage node, preferably the single point in the system where tight
voltage regulation is most beneficial.
2
—
PS
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 Figure 3-1).
—2
VDD
Power supply voltage input.
3
NC
Not connected.
4
GND
Ground terminal.
5
LX
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.
