Pin Function
Enable Input: CMOS and TTL logic compatible. Logic high = enable; Logic low
= shutdown.
Input voltage which supplies both the internal circuitry and the current to the
output load.
Ground
TAB is connected to ground.
Linear Regulator Output.
Error Flag Open collector output.
Active−low indicates an output fault condition.
Adjustable Regulator Feedback Input.
Connect to output voltage resistor divider central node.
Fixed Voltage Regulator Feedback Input.
Connect to output voltage node.
PAD for removing heat from the device. Must be connected to GND.
Not internally connected.
