5 Amp Dual Mode Low Dropout CMOS Regulator Features • • • • • • • • • • Adjustable Output or Internally Fixed 375mV dropout at 1.
5A load current Operates from 2.
2V to 5.
5V input supply Low Ground current (330µA at 1.
5A Load) Minimal output capacitance required Current Limit Protection Thermal Overload Protection Reverse Voltage Protection Thermally enhanced 8-pin SOIC package Lead-free versions available 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.
An Enable control pin (EN) allows the device to be placed in a low current mode.
Applications • • • • • Low Voltage "Core" processors Graphics Cards Gigabit NIC Cards PC Motherboards Notebooks 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, 8pin 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 leadfree finishing.
