Pin Functions

PIN I/O DESCRIPTION
NAME DBV NAME NGD
BYPASS 4 BYPASS 1 I Bypass capacitor for low-noise operation.
GND 2 GND 2 Ground.
IN 1 IN 4 I Unregulated input voltage.
N/C 5 No internal connection. Connect to GND or leave open.
ON/OFF 3 ON/OFF 3 I A low voltage on this pin disables the device, and the regulator enters a sleep mode. A high voltage on this pin enables the device.
OUT 5 OUT 6 O Regulated output voltage. This pin requires an output capacitor to maintain stability. See the Detailed Design Procedure for output capacitor details.
DAP Exposed thermal pad The exposed die attach pad on the bottom of the package must be connected to a copper thermal pad on the PCB at ground potential. Connect to ground potential or leave floating. Do not connect to any potential other than the same ground potential seen at device pin 2.
