NAME

IN
I
Input voltage supply. Connect a 1µF capacitor at this input.
A2
OUT
O
Regulated output voltage. Connect a minimum 1µF low-ESR capacitor to this pin. Connect
this output to the load circuit. An internal 230Ω (typical) pulldown resistor prevents a charge
remaining on VOUT when the regulator is in the shutdown mode (VEN low).
B1
EN
I
Enable input. A low voltage (< VIL) on this pin turns the regulator off and discharges the
output pin to GND through an internal 230Ω pulldown resistor. A high voltage (> VIH) on this
pin enables the regulator output. This pin has an internal 1MΩ pulldown resistor to hold the
regulator off by default.
