Key Features

  • 250mA output current with ultra-low 120mV typical dropout voltage
  • Ultra-low noise: 27µVRMS output noise for noise-sensitive applications
  • Quiescent current as low as 75µA enabling high efficiency in light-load scenarios
  • Fixed 1.8V output in compact SOT-23 5-pin package
  • Input voltage range: 2.2V to 5.5V, suitable for 3.3V and 5V supply rails

Applications

The LP5907MFX-1.8/NOPB is ideal for powering noise-sensitive analog and RF circuits, including ADCs, DACs, PLLs, and RF transceivers where supply noise directly impacts signal quality. It is widely used in portable and battery-powered devices such as wearables, IoT sensors, and handheld instruments that demand high efficiency and minimal quiescent current. Its compact SOT-23 footprint also makes it suitable for space-constrained designs in industrial and consumer electronics.
