EN

Enable pin. Driving this pin high enables the regulator. Driving this pin low puts the regulator into shutdown mode.

4

BIAS

Bias voltage supply for internal control circuits. This pin is monitored by internal Under-Voltage Lockout Circuit.

5

GND

Ground pin

6

IN

Input Voltage Supply pin

Pad

Should be soldered to the ground plane for increased thermal performance.
