Product Description

The CM3004 is a very-low-dropout regulator that offers both fixed output and fixed/adjustable operating modes. When the Adjust control pin (ADJ) is grounded, this device automatically enters a fixed voltage mode delivering 2.5V out at 1.0A. When the Adjust pin is connected to an external resistor network the device automatically operates as an adjustable regulator. The Adjust pin can also be tied directly to the OUT pin which configures the CM3004 as a 1.2V regulator.
