Supplier Device Package TSOT-23-5

The MAX8878EZK18-T from Analog Devices is a compact 1.8V low dropout linear regulator delivering up to 150mA. With an ultra-low quiescent current of 180 µA and a typical dropout of just 0.165V at full load, it is optimized for battery-powered and low-power applications. The TSOT-23-5 package is ideal for space-constrained designs.

  • Ultra-Low Quiescent Current: 180 µA extends battery life in portable devices.
  • Very Low Dropout: 0.165V at 150mA maximizes usable battery voltage.
  • Miniature Package: TSOT-23-5 fits into the smallest PCB layouts.
  • Stable Low-Voltage Output: Precise 1.8V rail for modern low-power digital ICs.
