MP20045DQ - 1A Linear Regulator

Download the MP20045DQ datasheet PDF. This datasheet also covers the MP20045 variant, as both devices belong to the same 1a linear regulator family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key Features

  • include low-power shutdown, short-circuit and thermal protection. The MP20045 is available in 8-pin QFN (3mm x 3mm) and SOIC8E packages. MP20045 Low Noise, 1A Linear Regulator.

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. MP20045 Low Noise, 1A Linear Regulator FEATURES  Up to 1A Output Current  Low 140mV Dropout at 1A  Low 110μA Ground Current  Fixed Output Versions Ranging from 1.
