Input
Enable pin. Drive EN greater than VEN(HI) to turn on the
regulator. Drive EN less than VEN(LO) to put the low-dropout
regulator (LDO) into shutdown mode.

Input
Input pin. For best transient response and to minimize input
impedance, use the recommended value or larger ceramic
capacitor from IN to ground as listed in the Recommended
Operating Conditions table and the Input and Output Capacitor
Selection section. Place the input capacitor as close to the
output of the device as possible.

Output
Regulated output voltage pin. A capacitor is required from OUT
to ground for stability. For best transient response, use the
nominal recommended value or larger ceramic capacitor from
OUT to ground; see the Recommended Operating Conditions
table and the Input and Output Capacitor Selection section.
Place the output capacitor as close to the output of the device as
possible.
