LDK220M32R ST LDO Regulator | SOT-23-5 | 3.2V Output, 200mA

Product Overview

The LDK220M32R from STMicroelectronics is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. Housed in a compact SOT-23-5 package, it delivers a fixed output voltage of 3.2V with a maximum output current of 200mA. The device features ultra-low quiescent current (1 µA typical) and high PSRR (55 dB at 1 kHz), making it ideal for battery-powered and noise-sensitive circuits.
