PIN FUNCTION DESCRIPTIONS

SOT-23-6 SO-8

Name

Function

Shutdown. Pulling this pin low

will disable the output.

GND

Device Ground. This pin should

be tied to system ground closest

to the load.

VOUT

Output Voltage Sense. This pin

is connected to the MOSFET’s

drain and directly to the load for

optimal load regulation. Bypass

to ground with a 10

µF or larger

capacitor.

GATE

Gate drive for the external

MOSFET.

VIN

Input Voltage. This is also the

positive terminal connection of

the current sense resistor.

Current Sense. Used to sense the

input current by monitoring the

voltage across the current sense

resistor. It is connected to the

more negative terminal of the

resistor as well as the power

MOSFET’s source pin. IS pin

should be tied to the VIN pin if

the current limit feature is not

used.
