MD73UXX Overview

73UXX 300mA enable side fast LDO

Features

The MD73UXX series is a positive voltage regulator circuit with low voltage dropout, high-precision output voltage, and ultra-low power consumption current developed using CMOS technology. Since it has a built-in low on-resistance transistor, the input-output voltage dropout is low. At the same time, it has a high input voltage tolerance, and the maximum operating voltage can reach 15V, which is suitable for application circuits that require higher withstand voltage.

Parameters

■ Maximum input voltage 15V

■ Output voltage range 1.8V~5.0V

　MD73U28, output voltage 2.8V (73U28);

　MD73U30, output voltage 3.0V (73U30);

　MD73U33, output voltage 3.3V (73U33);

　MD73U36, output voltage 3.6V (73U36);

　MD73U44, output voltage 4.4V (73U44);

　MD73U50, output voltage 5.0V (73U50).

■ Output current 300mA

■ Quiescent current 15uA

■ Accuracy ±2%

■ Package type: SOT-89, SOT-23

Application

■ Use a regulated power supply for battery powered devices

■ Regulated power supply for communication equipment

■ Stabilized power supply for home appliances and toys
