The MP2002AGD-Z from Monolithic Power Systems is a 500mA low dropout linear regulator delivering a fixed 5V output. Featuring a low typical dropout of 0.29V at full load, it efficiently regulates from higher input rails. The compact 8-QFN (2x3mm) package makes it suitable for space-constrained industrial and consumer applications requiring a stable 5V supply.

  • High Current Capacity: 500mA output supports a wide range of digital and analog loads.
  • Low Dropout Voltage: 0.29V typical dropout at 500mA reduces power loss and allows operation from lower input voltages.
  • Compact Footprint: The 2x3mm QFN package saves board space in dense designs.
  • Fixed 5V Output: Simplifies design by eliminating external resistor dividers.

5V Logic Rail Supply

Provides a stable 500mA 5V rail for microcontrollers, logic ICs, and peripheral interfaces in embedded systems.

Industrial Sensor Modules

The low 0.29V dropout ensures reliable 5V regulation from 5.5V or 6V input rails, common in industrial 24V-to-5V intermediate conversions.

Networking Equipment

Delivers clean 5V power to PHY chips and small switches, with the QFN package suitable for compact PCB layouts.

Audio Codec Power

Provides a low-noise 5V supply for audio codecs and DACs, minimizing hum and distortion in portable audio gear.

FPGA Auxiliary Supply

Regulates 5V for FPGA I/O banks or auxiliary circuits, offering a cost-effective alternative to switching regulators where efficiency is less critical.

Automotive Infotainment

With a wide input tolerance, it can power 5V logic in aftermarket infotainment systems from a regulated 6V source.
