MP2019
40V, 300mA, Low Quiescent Current
Adjustable Output Linear Regulator
DESCRIPTION
FEATURES
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

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).
Available in a SOIC-8 EP Package
The regulator output current is limited internally,
and the device is protected against short-circuit,
over-load, and over-temperature conditions.
