MP20045DN Overview
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.
