Function
Enable. Pull high to enable the output, low to disable the output. This pin has no internal bias
and must be tied to the input voltage, or actively driven.
Input Supply Pin
Ground
Regulated Output Voltage Pin
ERROR Flag. A high level indicates that V_OUT is within 15% (V_OUT falling) of the nominal
regulated voltage.
The TO-263 TAB, and the TO-263 THIN DAP, is used as a thermal connection to remove
heat from the device to an external heatsink. The TAB/DAP is internally connected to device
pin 3, and is electrical ground connection.
