R5328K Series

Low Voltage 3-Mode Dual 150mA LDO

Data Sheet / Flyer
Data Sheet * Flyer

The R5328K Series are dual 150mA voltage regulator ICs with 3-mode. The 3-mode describes that they are the inactive standby, the active fast mode, and the active low power mode. The two active modes can be switched over with ECO pin. With this function, the output voltage maintains the level, and the mode can be switched over.

The minimum operating voltage is 1.4V, and the output voltage range is from 0.8V to 4.0V.

Since the package for these ICs is DFN(PLP)2020-8, high density mounting of the ICs on boards is possible.
