Pin Functions

PIN I/O DESCRIPTION
NAME NO.
EN 2 I Enable input. Pulling this pin below 0.5 V turns the regulator off. Connect to VIN if not being used.
FB 7 I This pin is the output voltage feedback input through voltage dividers. See the Table 2 for more details.
GND 8 – Ground pin
IN 3 I Unregulated supply voltage pin. It is recommended to connect an input capacitor to this pin.
NC 1, 4, 5 – Not internally connected. The NC pins are not connected to any electrical node. It is recommended to connect the NC pins to large-area planes.
OUT 6 O Regulated output pin. A 4.7-μF or larger capacitor of any type is required for stability.
PowerPAD TI strongly recommends connecting the thermal pad to a large-area ground plane. If an electrically floating, dedicated thermal plane is available, the thermal pad can also be connected to it.
