Pin Descriptions

2
EN 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.
3
VIN Input voltage. For regulation at full load, the input to this pin must be between (VO+ 0.5V) and 5.5V.
Minimum VIN = 1.45V. A large bulk capacitance should be placed closely to this pin to ensure that
the input supply does not sag below 1.45V. Also a minimum of 4.7uF ceramic capacitor should be
placed directly at this pin.
6
VO The pin is the power output of the device. A minimum of 10uF capacitor should be placed directly at
this pin.
7
FB
When this pin is grounded, an internal resistor divider sets the output voltage to 1.2V. If connected
to the Vo pin, the output voltage will be set at 0.5V. If external feedback resistors are used, the output
voltage will be (See Application Circuits on page 1):
