Product Description

The MP2019 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 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 1.2V to 15V).
The regulator output current is limited internally, and the device is protected against short-circuit, over-load, and over-temperature conditions.
The MP2019 includes thermal shutdown (TSD), current-limiting fault protection, and is available in a SOIC-8 EP package.

40V, 300mA, Low Quiescent Current Linear Regulator Evaluation Board

The EV2019-5-N-00A is an evaluation board for the MP2019-5/MPQ2019-5, a low linear regulator that supplies power to systems with high voltage batteries.

MP2019-5/MPQ2019-5 includes a wide 6V 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 MP2019-5/MPQ2019-5 is ideal for the low power microcontrollers and the battery-powered equipments.

The EV2019-5-N-00A is a fully assembled and tested evaluation board. It generates a +5V output voltage at load current up to 300mA from a 6V to 40V input range.
