Product 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 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-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.

IC Details

The MP2005 is a micropower, ultra low-dropout LDO linear regulator. It has a 1.0V to 5.5V input voltage range and can regulate the output voltage from as low as 0.5V. The MP2005 can supply up to 800mA of load current with a typical dropout voltage of 90mV. It requires a bias supply (2.7V 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 wide range of voltages (0.5V to 4V). A low bias current of 100? makes the MP2005 ideal for use in battery-powered applications. The bias supply VBIAS can be directly applied from the battery while VIN is powered from the high efficiency buck regulator (or other secondary supply). This reduces output noise and the size of the decoupling capacitor. Other features of MP2005 include thermal overload and current limit protection, stability with ultra low ESR ceramic capacitors as low as 1?, and fast transient response. The MP2005 is available in a 8-pin QFN (2mm x 3mm) package.
