Linear Regulator

The Future of Analog IC Technology

DESCRIPTION

FEATURES

•

Up to 1A Output Current

Low 140mV Dropout at 1A

Low 110µA Ground Current

Fixed Output Versions Ranging from 1.5V to

5V and Adjustable Versions

Open Drain Power-Good Status Output

13µV_RMSLow Noise Output

56dB PSRR at 1kHz

Current Limiting and Thermal Protection

3mm×3mm QFN8 and SOIC8E Packages

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.
