This IC is a 150 mA LDO featuring automatic power-saving.
This device automatically switches between a high-speed operation mode and low-power mode depending on the load current. In the low power mode, current consumption is lowered to 4.5 µA.
This device is suitable for cell-phones which require low power consumption in standby mode and other such applications.
