Pin Functions

PIN I/O DESCRIPTION
NAME NO.
VOUT A1, A2 O Power output pin. Apply output load between this pin and GND.
VIN A3, B3 I Supply voltage connection
EN B2 I This is the enable pin of the device. Connecting this pin low forces the device into shutdown mode. Pulling this pin high enables the device. This pin must not be left floating and must be terminated.
MODE B1 I This pin must be tied to the input supply voltage VIN.
GND C1, C2, C3 – Ground pin.
