DESCRIPTION

1

SENSE

Allows Kelvin sense of VOUT at the load. (Positive side of the

reference voltage of the device).

2

ADJ

Negative side of the reference voltage for the device. Adding a small

bypass capacitor from the ADJ pin to ground will improve the transient

response.

3

VOUT

Power output of the device.

4

VCTRL

Supply pin for the control circuitry of the device. The current flow into this

pin will be about 1% of the output current. VCTRL must be between 1.0V

and 1.3V greater than the output voltage for the device to regulate.

5

VIN

Output load current is supplied through this pin. VIN must be between 0.1V

and 0.8V greater than the output voltage for this device to regulate.
