FUNCTION
Feedback Input. Connect FB to GND for a 1.8V output. Connect FB to IN for a 1.9V output. Do not leave FB
unconnected.
Active-Low Shutdown Input. Connect to logic control or to IN for normal operation. OUT disconnects from the
input in shutdown and goes to high impedance.

Output. Bypass to GND with a 4.7μF or greater capacitor.
Input Supply. Connect to a +2.7V to +5.5V supply. Bypass to GND with a 1μF ceramic capacitor as close to
the IC as possible.
