MP2002 Datasheet, PDF (1/11 Pages) Monolithic Power Systems – Low Input Voltage 500mA Linear Regulator

The Future of Analog IC Technology
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
