Pin Functions

PIN I/O DESCRIPTION
NAME SOT23-5 X2SON-4
EN 3 3 I Enable input. A low voltage (< VIL) on this pin turns the regulator off and discharges the output pin to GND through an internal 230-Ω pulldown resistor. A high voltage (> VIH) on this pin enables the regulator output. This pin has an internal 1-MΩ pulldown resistor to hold the regulator off by default.
GND 2 2 – Common ground
IN 1 4 I Input voltage supply. Connect a 1-µF capacitor at this input.
N/C 4 — – No internal electrical connection.
OUT 5 1 O Regulated output voltage. Connect a minimum 1-µF low-ESR capacitor to this pin. Connect this output to the load circuit. An internal 230-Ω (typical) pulldown resistor prevents a charge remaining on VOUT when the regulator is in the shutdown mode (VEN low).
