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

1.25V 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.
