MM4047

MinebeaMitsumi's linear regulators (LDOs) are developing distinctive products that take advantage of the strengths of CMOS processes and bipolar processes. Supports output current from 100mA to 1.5A, and in addition to functions including soft start, backflow protection, and auto discharge, we also have a lineup of products with special functions such as output current detection and temperature sensor output to meet customers needs.

Overview

This IC is ultra low noise LDO capable of supplying 450mA output current. Designed to meet the requirements of RF circuits, Image sensor and high resolution audio codec, the device provides low noise, High PSRR. It is available in WLCSP (0.65 mm×0.65 mm) and PLP-4 (1.0mm×1.0mm), which are suitable for smartphones, wireless earphones and wearable devices.
