DESCRIPTION

The MP2002 is a low-current, low-dropout

linear regulator operating over a single input

supply between 1.35V to 6.5V. The output

voltage of the MP2002 is adjustable via an

external resistor divider. The MP2002 can

supply up to 500mA of load current. The enable

pin (EN) allows the part to be put into a low

current shutdown mode (EN=0). The MP2002

features thermal overload and current limit

protection. It is available in an 8-pin QFN (2x

3mm) package
