Monolithic Power Systems
DESCRIPTION
The MP2019 is a low-power linear regulator that supplies power to systems with highvoltage batteries. It includes a wide 3V to 40V input range, low-dropout voltage, and a low quiescent-supply current. The low quiescent current and low dropout voltage allow operations at extremely low-power levels. Therefore, the MP2019 is ideal for low-power microcontrollers and battery-powered equipment.
The MP2019 provides a wide variety of fixed output-voltage options (if requested): 1.8V, 1.9V, 2.3V, 2.5V, 3.0V, 3.3V, 3.45V, and 5.0V; also, it provides the output-adjustable option (from 1.25V to 15V).
