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 a 1A LDO with Over current detection and OCP auto-retry function. The over current detection function can set threshold current by the external resister Rsc and output an error flag when the load current over the threshold current.The OCP auto-retry function enables overcurrent protection to operate intermittently, greatly reducing heat generation during overcurrent.
