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 con-
nected to an external resistor network the device auto-
matically 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.
An Enable control pin (EN) allows the device to be
placed in a low-current mode.
The CM3004 is fully protected, offering both overload
current limiting, short-circuit protection and high-tem-
perature thermal shutdown. The CM3004 also includes
protection against output to input current flow while in
shutdown.
The CM3004 is supplied in a space-saving, 8-lead
power SOIC package which has been thermally
enhanced via an integral leadframe to ensure maxi-
mum junction-to-ambient power dissipation. The
CM3004 is also available with optional lead-free finish-
ing.
