Pin Functions

SHDN (Pin 1): Shutdown Input. This active low input

powers down the device to <20µA. If left open, an inter-

nal pull-up resistor puts the part in normal operation. It

is recommended to tie this pin high externally for best

performance during normal operation.

VIN (Pin 2): Power Supply. Bypass VIN with a 0.1µF, or

larger, capacitor to GND.

GND (Pin 4): Device Ground. This pin is the main ground

and must be connected to a noise-free ground plane.

VOUT_S (Pin 6): VOUT Sense Pin. Connect this pin at the

load and route with a wide metal trace to minimize load

regulation errors. This pin sinks 2mA. Output error is

RTRACE • 2mA, regardless of load current. For load currents

<100µA, tie directly to VOUT_F pin.

VOUT_F (Pin 7): VOUT Force Pin. This pin sources and

sinks current to the load. An output capacitor of 2.7µF to

100µF is required.

GND (Pins 3, 5, 8): Internal Function. Ground these

pins.
