DESCRIPTION

The

EV2005DD-01B

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 500mA 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-01B provides thermal overload

and current limit protection, stability with ultra

low ESR ceramic capacitors, 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.
