Regulator Input. Supply voltage can range from 2.5V to 5.5V. Bypass with a 1µF capacitor to GND.
Ground.
Shutdown Input. A logic low reduces the supply current to 10nA. Connect to IN for normal
operation.
Reference-Noise Bypass(fixed voltage version only). Bypass with a low-leakage 0.01µF ceramic
capacitor for reduced noise at the output.
Adjustable voltage version only—this is used to set the output voltage of the device.
Regulator Output.
