FUNCTION
Input Supply Pin. VIN can range from 2.5V to 5.5V and should be bypassed with
at least a 1µF capacitor.
Enable Input. Pulling the VEN1/2 above 1.5V enables the respective regulator
output; pulling VEN1/2 below 0.4V disables the respective regulator output.
Ground.
Regulator Outputs. Sources up to 300mA. Bypass with at least a 1µF capacitor
to the GND respectively.
Exposed Pad. Connect it to a large ground plane for heatsinking.
