MPQ2019
40V, 300mA, Low-Quiescent Current
Adjustable Output Linear Regulator
AEC-Q100 Qualified
DESCRIPTION
FEATURES
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
3V to 40V Input Range

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
1.25V to 15V).
Available in a SOIC-8 EP Packages
Available in AEC-Q100 Grade 1
The regulator output current is limited internally,
and the device is protected against short-circuit,
over-load, and over-temperature conditions.
APPLICATIONS
The MPQ2019 includes thermal shutdown
(TSD), current-limiting fault protection, and is
available in a SOIC-8 EP package.
