Regulated Output Voltage. Only a low-value ce

ramic capacitor (≥ 0.47μF) on the output

is required for stability.

2

NC

No Connection. Do NOT connect.

3

GND

Ground. Connect the exposed pad and GND to the same ground plane.

4

VIN

Input Voltage. Connect a 3V to 40V supply to VIN.

5

Regulator On/Off Control Input. Logic low shuts down the IC; logic high starts up the IC.

Connect EN to VIN for automatic start-up.

6

PG

Power Good. If not used, pin can be left floating.

7

PGDL

Programmable Power-Good Delay Time. If not used, pin can be left floating.

8

FB

Feedback Input for Output Adjustable Version. FB is regulated to 1.25V nominally. This

terminal is used to set the output voltage.
