DESCRIPTION

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

reference voltage of the device).

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.

Power output of the device.

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.

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.

Note that TAB is internally connected to Pin 3.
