ST1PS01AJR ST 电源管理IC | 8-覆晶（1.11x1.41） | 3.6V输入, 1.8V输出

Product Overview

The ST1PS01AJR is a step-down switching regulator from STMicroelectronics, designed for ultra-compact power management in portable and space-constrained applications. Housed in a tiny 8-覆晶 (Flip Chip) package measuring just 1.11x1.41 mm, it integrates a high-efficiency DC-DC converter with a typical input voltage range of 2.3V to 5.5V and a fixed output voltage of 1.8V. The device delivers up to 400 mA output current with excellent load and line regulation, making it ideal for powering low-voltage digital cores, sensors, and wireless modules.
