2μA IQ, 600mA Low-Dropout Linear Regulator

RT9080

Update Alert Share

The RT9080 is a low-dropout (LDO) voltage regulators with enable function that operates from 1.2V to 5.5V. It provides up to 600mA of output current and offers low-power operation in miniaturized packaging.

The features of low quiescent current as low as 2μA and almost zero disable current is ideal for powering the battery equipment to a longer service life. The RT9080 is stable with the ceramic output capacitor over its wide input range from 1.2V to 5.5V and the entire range of output load current (0mA to 600mA).

Applications

  • Portable, Battery Powered Equipment
  • Ultra Low Power Microcontrollers
  • Notebook Computers
