Product Description
The CM3003 is a family of very low dropout regulators
that offers dual mode operation. When the Adjust con-
trol 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.
An Enable control pin (EN) allows the device to be
placed in a low current mode.
The CM3003 devices are fully protected, offering both
overload current limiting, short circuit protection and
high temperature thermal shutdown. These devices
also includes reverse voltage protection that minimizes
any reverse current flow back into the output pin.
The CM3003 devices are housed in a space saving, 8-
pin power SOIC packages which has been thermally
enhanced (integral leadframe) to ensure maximum
junction to ambient power dissipation.
The CM3003 devices are available with optional lead-
free finishing.
