1

Active Low Shutdown Input. Connect to VIN or a logic level high to enable the device. An internal

GND

2

Ground. Connect to the local analog ground or to the circuit board ground plane to maximize thermal

dissipation. Bypass the input and output capacitors to this plane.

VIN

3

Regulator Input. Operating voltage range is from 2.5V to 6V. Bypass VIN to GND with a 1uF

capacitor.

VOUT

4

Regulator Output. Bypass to GND with a 1uF capacitor.

(Adjustable

Output Version)

5

Feedback Input. For the adjustable output version (LX8213-00), the device output voltage can be set

from 1.2V to 5.5V by connecting FB to the center of a resistive voltage divider from VOUT to GND.

Note that FB regulates to 0.8V.
