The Future of Analog IC Technology
DESCRIPTION
The MP20045 is a low-dropout linear regulator
supplies up to 1A current with 140mV dropout
voltage. The output voltage is set externally
which ranges from 1.5V to 5V by operating from
+2.5V to +5.5V input or can be preset internally
from 1.5V to 5V.
An internal PMOS pass element is used to
allow a low 110μA ground current, making the
MP20045 suitable for battery-power devices.
Other features include low-power shutdown,
short-circuit and thermal protection. The
MP20045 is available in 8-pin QFN (3mm x
3mm) and SOIC8E packages.
