DESCRIPTION:
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 100µA 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 1μF, and fast transient response. The MP2005 is available in a
8-pin QFN (2mm x 3mm) package.
