DESCRIPTION
The EV8904DD-00A evaluation board
demonstrates the performance of MP8904, a
monolithic low-current, low-dropout LDO linear
regulator. It operates from a 2.5V to 6.5V input
bias voltage and regulates the output voltage
from as low as 0.5V.
It requires a bias supply (2.5V to 6.5V) separate
from V
IN
to run the internal reference and LDO
drive circuitry. The output current comes
directly from the input voltage supply for high
efficiency regulation. The 0.5V internal
reference voltage allows the output to be
programmed to a range of 0.5V to 5V.
The EV8904DD-00A provides thermal overload
and current limit protection. The MP8904 is
available in an 8-pin QFN (2mm x 3mm)
package.
