Pin Function
Enable Input. Pulling this pin below 0.4V turns the regulator off, reducing the quiescent current to
a fraction of its operating value. The device will be enabled if this pin is left open. Connect to VIN if
not being used.
Input voltage. For regulation at full load, the input to this pin must be between (VO+ 0.5V) and
5.5V. Minimum VIN = .6V. A large bulk capacitance should be placed closely to this pin to ensure
that the input supply does not sag below .6V. Also a minimum of 4.7uF ceramic capacitor should
be placed directly at this pin.
The pin is the power output of the device. A minimum of 0uF capacitor should be placed directly
at this pin.
When this pin is grounded, an internal resistor divider sets the output voltage to 2.5V. If connected
to the Vo pin, the output voltage will be set at 0.8V. If external feedback resistors are used, the
output voltage will be determined by the resistor ratio (See Application Circuits on page ):
Reference ground. The GND pin and the exposed die pad must be connected together at the IC
pin.
No Connection.
Pad for heatsinking purposes. Connect to ground plane using multiple vias.
