Pin Description

Pin Number

Pin Name

Pin Function

1, 2

IN

Input Voltage.

3

GND

Ground: Input and output return pin.

4

EN

Enable: Active-high control input that allows turn-on/-off of the LDO.

5, 6

NC

No external function. Tie to ground.

7

CP

Internal Charge Pump Circuit Output: Connect a 0.1µF to 1µF capacitor from CP pin-to-GND to

control the ramp rate of the output.

FB

Adjustable Regulator Feedback Input: Connect to the resistor voltage divider network that is

placed from OUT pin to GND pin in order to set the output voltage.

8

SENSE

Fixed-Output Voltage Sense Input: Apply a Kelvin connection from this pin of the fixed output at

the point-of-load to sense the output voltage level.

9, 10

OUT

(with the divided connection tied to FB). A 47µF ceramic capacitor with low ESR is required to

maintain stability. See Applications Information.

EP

GND

Connect to GND.
