DESCRIPTION

The

EV2005DD-00A

evaluation

board

demonstrates the performance of MP2005, a

monolithic low-current, low-dropout LDO linear

regulator. It operates from a 2.5V to 5V input

bias voltage and regulates the output voltage

from as low as 0.5V.

The EVB can supply up to 800mA of load

current with a typical dropout voltage of 75mV.

It requires a bias supply (2.5V to 5.5V) separate

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 EV2005DD-00A provides thermal overload

and current limit protection, stability with ultra

low ESR ceramic capacitors as low as 1uF, and

fast transient response. The MP2005 is

available in a 8-pin QFN (2mm x 3mm) package

and is also available in fixed output voltage

versions.
