Function
By applying less than 0.4 V to this pin, the device will be turned off. Connect this pin to V_IN if unused
The open drain output is an error flag output which goes low when V_OUT drops 4% below its nominal voltage.
Input supply pin. Bypass this pin with a 1-mF ceramic or tantalum capacitor to ground
Output voltage. Connect C_OUT between this pin and ground.
Ground pin. For better thermal capability, directly connected to large ground plane
