PIN DESCRIPTIONS

PIN(S)

NAME

DESCRIPTION

1

EN

2

IN

Positive input voltage for the regulator. If this input pin is greater than 2 inches from the main input

filter, a 10

µF ceramic capacitor is recommended for adequate filtering.

3

OUT

The regulated voltage output. An output capacitor of 10

µF is recommended to minimize any tran-

sient load disturbances under normal operating conditions. Additional output capacitance can be

used to further improve transient load response.

4

ADJ

Feedback input. When ADJ is grounded, the device enters fixed voltage mode. When ADJ is con-

nected to an external resistor network, the device operates as an adjustable regulator. The Adjust

pin can also be tied directly to the OUT pin which configures the CM3003 as a 1.2V regulator.

5-8

GND

The negative reference for all voltages. Also functions as a thermal path for heat dissipation.
