Input

Enable pin. Drive EN1 greater than VEN1(HI) to turn on the regulator.

Drive EN1 less than VEN1(LO) to put the low-dropout (LDO) regulator into

shutdown mode.

EN2

Input

Input pin. For best transient response and to minimize input impedance, use

the recommended value or larger ceramic capacitor from IN to ground; see 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.

Input pin. For best transient response and to minimize input impedance, use

the recommended value or larger ceramic capacitor from IN to ground; see 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 output of the device as

possible.

Output

Regulated output voltage pin. A capacitor is required from OUT to ground for

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 output of the device as

possible.
