LDK120M18R ST LDO Regulator | SOT-23-5 | 200mA, 1.8V Output

Product Overview

The LDK120M18R from STMicroelectronics is a high-performance, low-dropout (LDO) voltage regulator designed for space-constrained applications. Housed in a compact SOT-23-5 package, it delivers a fixed output voltage of 1.8V with a maximum output current of 200mA. The device features ultra-low quiescent current (30µA typical) and high PSRR (55dB at 1kHz), making it ideal for battery-powered and noise-sensitive systems. Its wide input voltage range (2.5V to 6V) ensures compatibility with various power sources.
