LDK130PU18R ST LDO Regulator | 6-DFN (1.2x1.3) | 1.8V Output, 300mA

Product Overview

The LDK130PU18R is a low-dropout (LDO) linear voltage regulator from STMicroelectronics, offering a fixed output voltage of 1.8V with a maximum output current of 300mA. Housed in a compact 6-DFN (1.2x1.3) package, it is designed for space-constrained applications requiring high efficiency and low noise. The device features a very low dropout voltage (typically 200mV at 300mA) and a quiescent current of only 30µA, making it ideal for battery-powered systems. With an input voltage range from 2.5V to 5.5V, it supports a wide variety of power sources.
