Product Description

The MPQ2019 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 MPQ2019 is ideal for low-power microcontrollers and battery-powered equipment. The MPQ2019 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 1.2V to 15V). The regulator output current is limited internally, and the device is protected against short-circuit, over-load, and over-temperature conditions. The MPQ2019 includes thermal shutdown (TSD), current-limiting fault protection, and is available in a SOIC-8 EP package.
