ST1L05APU33R ST LDO Regulator | 6-DFN (3x3) | 3.3V Output, 1A Current

Product Overview

The ST1L05APU33R is a high-performance low-dropout (LDO) linear voltage regulator from STMicroelectronics, offering a fixed output voltage of 3.3V and a maximum output current of 1A. Housed in a compact 6-DFN (3x3 mm) package, it is designed for space-constrained applications requiring low noise and high efficiency. The device features a low dropout voltage of typically 300mV at full load, making it suitable for battery-powered systems. With an input voltage range from 2.5V to 6V, it provides a stable output with high accuracy (±1%). The ST1L05APU33R integrates protection features such as overcurrent and thermal shutdown, ensuring reliable operation in demanding environments.
