40V, 500mA, Low Quiescent Current Linear Regulator



The MP2014 is a low power linear regulator that supplies power to systems with high voltage batteries. It includes a wide 3V to 40V input range, low dropout voltage and low quiescent supply current. The low quiescent current and low dropout voltage allow operations at extremely low power levels. Therefore, the MP2014 is ideal for the low power microcontrollers and the battery-powered equipments.
The MP2014 provides wide variety of fixed output voltage options (if request): 1.8V, 1.9V, 2.3V, 2.5V, 3.0V, 3.3V, 3.45V, 5.0V.
The regulator output current is internally limited and the device is protected against short-circuit, over-load and over-temperature conditions.
The MP2014 also includes thermal shutdown and current limiting fault protection, and is available in TO252-5 package.
