ST1PS02BQTR ST Power Management IC | 12-TQFN (1.7x2) | 1.8V-5.5V Input, 400mA Output

Product Overview

The ST1PS02BQTR is a high-efficiency, low-quiescent current step-down converter from STMicroelectronics, designed for space-constrained and battery-powered applications. Housed in a compact 12-TQFN (1.7x2 mm) package, it integrates a synchronous rectifier and operates from an input voltage range of 1.8V to 5.5V, delivering up to 400mA output current. The device features a typical quiescent current of 1.5 µA, making it ideal for always-on systems. With a switching frequency of 1.5 MHz, it allows the use of small external components, reducing overall solution size.
