NAME

DESCRIPTION

LEAD(S)

1

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.

2, TAB

5-8

GND

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

sipation.

3

OUT

The regulated voltage output. An output capacitor of 10

µF is recommended to mini-

mize any transient load disturbances under normal operating conditions. Additional

output capacitance can be used to further improve transient load response.

---

1

EN

Enable/shutdown input. When EN is asserted high (VEN ≥ 1.2V), the regulator is

enabled. When EN is asserted low (VEN ≤ 0.4V), the regulator is shut down.

---

4

ADJ

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

ADJ is connected to an external resistor network, the device operates as an adjust-

able regulator. The Adjust pin can also be tied directly to the OUT pin which config-

ures the CM3065 as a 1.2V regulator.
