DESCRIPTION
Positive input voltage for the regulator. If this input pin is greater than 2 inches from
the main input filter, a 10µF ceramic capacitor is recommended for adequate filtering.
The negative reference for all voltages. Also functions as a thermal path for heat dis-
sipation.
The regulated voltage output. An output capacitor of 10µF 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.
Enable/shutdown input. When EN is asserted high (V_EN ≥ 1.2V), the regulator is
enabled. When EN is asserted low (V_EN ≤ 0.4V), the regulator is shut down.
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.
