■Overview
< MM3416 >, Mitsumi has developed an ultra-low saturation CMOS series regulator IC having a fast response as well as a low current consumption and small size.
In addition to having a low dropout suitable for a fast transient response, the IC has a reduced quiescent current of 42 µA typ. and high ripple rejection of 75 dB typ. It is therefore particularly suitable for the power supply in applications where noise can be problem, such as in the CCD in cameras and RF in cell phones.
The IC has a built-in soft start function and is therefore capable of reducing the inrush current at start-up. The IC will be available in PLP-4 packaging for high-density mounting and in two other types of packaging.
