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 from VIN 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 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.
