Output pin. A 2.2-μF ceramic capacitor is connected from this pin to ground, for stability and to provide

load transients. See Input and Output Capacitor Requirements.

I

Enable pin. A logic high signal on this pin turns the device on and regulates the voltage from IN to

OUT. A logic low on this pin turns off the device.

Bias supply pin. TI recommends bypassing this input with a ceramic capacitor to ground for better

transient performance. See Input and Output Capacitor Requirements.

I

Input pin. This pin can be a maximum of 4.5 V; VIN must not exceed VBIAS. Bypass this input with a

ceramic capacitor to ground. See Input and Output Capacitor Requirements.

(1)

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

To ensure proper operation of the device it is necessary that VIN ≤ VBIAS under all conditions.

(3)

Whichever is less.

(4)

For durations no longer than 1ms each, for a total of no more than 1000 occurrences over the lifetime of the device.
