Product Description

The CM3003 is a family of very low dropout regulators that offers dual mode operation. When the Adjust control pin (ADJ) is grounded, these devices automatically enter a fixed voltage mode and deliver either a 1.8V or 2.5V output capable of supplying 1.5A, depending on the device utilized. 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 CM3003 as a 1.2V regulator.
