1. Pin Assignment and Functions

Top view

Pin Name

Description

IN

Input voltage supply pin.

GND

Power supply ground.

EN

Enable pin. This pin has a 100 nA pull-down current source. Connect to logic high for normal

operation.

NC

Do not connect.

OUT

Regulated output voltage. Bypassed the output with a small 1 µF ceramic capacitor.

Thermal PAD

Exposed Pad. Exposed pad can be tied to ground plane for better power dissipation.

2. Absolute Maximum Ratings

Exceeding the maximum ratings listed under Absolute Maximum Ratings when designing is likely to

damage the device permanently. Do not design to the maximum limits because long-time exposure to them

might impact the device’s reliability. The ratings are obtained over an operating free-air temperature range

unless otherwise specified.
